o support for the new codepage-aware ansistrings in the jvm branch
o empty ansistrings are now always represented by a nil pointer rather than
by an empty string, because an empty string also has a code page which
can confuse code (although this will make ansistrings harder to use
in Java code)
o more string helpers code shared between the general and jvm rtl
o support for indexbyte/word in the jvm rtl (warning: first parameter
is an open array rather than an untyped parameter there, so
indexchar(pcharvar^,10,0) will be equivalent to
indexchar[pcharvar^],10,0) there, which is different from what is
intended; changing it to an untyped parameter wouldn't help though)
o default() support is not yet complete
o calling fpcres is currently broken due to limitations in
sysutils.executeprocess() regarding handling unix quoting and
the compiler using the same command lines for scripts and directly
calling external programs
o compiling the Java compiler currently requires adding ALLOW_WARNINGS=1
to the make command line

val/str for enums for now) for the JVM target: insert/delete/pos/...
* use generic unicodestring helper routines where possible for the JVM
target (not that many as for shortstrings since unicodestring is
handled using java.lang.String)
+ complete widestring manager implementation for the JVM target. It uses
a class with virtual methods rather than a record with function pointers
for speed reasons though (since no existing widestring manager will be
compatible anyway, that shouldn't cause any problems)

* fixed FpcBaseProcVarType.clone: create a new method field "pointer" and
set it (using the java.lang.reflect interface). Previously, the pointer
to the method record was copied via the inherited clone, which meant
that the original and new procvar shared it

in the system unit for easier debugging)
* disabled a bunch more feature flags by default for the JVM target
* incorporate modified version of inc/systemh.inc (split into two parts:
jsystemh_types.inc and jsystemh.inc, because some of the types are
required for the declaration of the shortstring/ansistring/set/...
classes, which in turn are required for the routine declarations) and
inc/system.inc (as jsystem.inc)
o moved some routines around from old to new locations based on where
they appear in the common files
o added a number of defines that allow skipping more common implementations
in case a platform-specific one is already available
* all base classes (AnsistringClass etc) are now descendants of
JLObject rather than TObject, because their declaration is now parsed
before TObject is known (and there's no need for them to inherit from
TObject)
* incorporate modified version of inc/system.inc
* use the common version of generic.inc, currh.inc, gencurr.inc and
genmath.inc (with small modification to those files)
+ addition of quite a bit of system unit functionality (halt, runerror,
random, round, str() for integer types, abs, odd, endian swapping helpers,
bit scanning, trigonometric functions, ln, exp, ...)
o round()/trunc() for comp-types has been renamed trunc_comp() on the
JVM target because their JVM signature conflicts with trunc(currency)
o the unsigned versions of swapendian() and other endian helpers are not
available on the JVM target because of JVM signature conflicts

+ include mathh.inc in the system unit, implement most routines based
on java.lang.Math, and use (an unmodified!) genmath for the rest
- removed now obsolete jmathh.inc (was partial copy of mathh.inc)
- removed commented out overrides for several math routines in
njvminl (doesn't make sense to handle them inline in the compiler)

* catch java.lang.NoSuchMethodException exceptions when resolving a procvar,
because java.lang.Class.getDeclaredMethod() only searches that particular
class itself and not its parents -> in case we get the address of a method
that's not overridden in the current class, also search the parent classes

o every porocedural variable type is represented by a class with one
public "invoke" method whose signature matches the signature of the
procvar
o internally, dispatching happens via java.lang.reflect.Method.invoke().
WARNING: while this allows calling private/protected or other methods
that are normally not accessible from another context, a security
manger can override this. If such a security manager is installed,
most procvars will cause security exceptions
o such dispatching also requires that all arguments are wrapped, but
that's done in the compiler-generated body of the invoke method,
so that procvars can also be called conveniently from Java code
o typecasting between a procedure of object and tmethod is supported,
as well as Delphi-style replacing of only the method pointer via
@procvar1=@procvar2.
o nested procvars are not yet supported, but most of the basic
infrastructure for them is already present
* all units/programs now get an internal __FPC_JVM_Module_Class_Alias$
type when compiled for the JVM target, which is an "external" class
that maps to the unit name. This is required to look up the
JLRMethod instances for regular functions/procedures
+ new tabstractprocdef.copyas() method that allows to create a procvar
from a procdef and vice versa

o sets of enums are handled as JUEnumSet instances, others as JUBitSet
derivatives (both smallsets and varsets, to make interoperability with
Java easier)
o special handling of set constants: these have to be constructed at run
time. In case of constants in the code, create an internal constsym to
represent them. These and regular constsyms are then aliased by an
another internal staticvarsym that is used to initialise them in the
unit initialisation code.
o until they are constructed at run time, set constants are encoded as
constant Java strings (with the characters containing the set bits)
o hlcgobj conversion of tcginnode.pass_generate_code() for the genjumps
part (that's the only part of the generic code that's used by the JVM
target)
o as far as explicit typecasting support is concerned, currently the
following ones are supported (both from/to setdefs): ordinal types,
enums, any other set types (whose size is the same on native targets)
o enum setdefs also emit signatures
o overloading routines for different ordinal set types, or for different
enum set types, is not supported on the JVM target

* migrated some types that will be required for set support from jdk15
to java_sys

o these classes get an "enum" flag in the class files
o these classes get a class field (whose type is that same enum
class) per enum in the type, which also gets the "enum" flag
o those class fields are initialised in the class constructor
with the name of the enum and their order in the declaration
o if the enum has jumps in FPC (lowest value is not 0, or not
all values are contiguous), then we add an extra field
to hold the FPC ordinal value of the enum
o these classes get a class field valled $VALUES that contains
a reference to the aforementioned class fields in order of
declaration (= ordinal->instance mapping, JDK-mandated)
o apart from the JDK-mandated instance methods (values, valueOf),
also add FPCOrdinal (returns FPC ordinal value; same as order
of declaration in case of no jumps) instance method and FPCValueOf
(returns enum corresponding to FPC ordinal value) static class
method
o the mapping between FPC ordinals and enum instances in case of
jumps is stored in a hashmap whose size is the next prime number
greater or equal than the number of enum elements
o moved several extra JDK types to the system unit for the enum
support, and for future boxing and Java set support
o several new synthetic method identifiers to generate the enum class
methods/constructor/class constructor
o enums with jumps are ordered by FPC ordinal value in the JVM
$VALUES array so that the java.lang.Enum.doCompare() method
will properly compare them

o support for ansistring constants. It's done via a detour because the
JVM only supports UTF-16 string constants (no array of byte or anything
like that): store every ansicharacter in the lower 8 bits of an
UTF-16 constant string, and at run time copy the characters to an
ansistring. The alternative is to generate code that stores every
character separately to an array.
o the base ansistring support is implemented in a class called
AnsistringClass, and an ansistring is simply an instance of this
class under the hood
o the compiler currently does generate nil pointers as empty
ansistrings unlike for unicodestrings, where we always
explicitly generate an empty string. The reason is that
unicodestrings are the same as JLString and hence common
for Java interoperation, while ansistrings are unlikely to
be used in interaction with external Java code
* fixed indentation
