handling in cross-configuration with different endianess.
The code has been modified to use the same scheme as the writing of
the other parts of the ppu, i.e. change_endian filed has been
added also to tscannerfile class of scanner unit.
This field is then used to swap values that required endianess
conversion.
* scanner.pas: change_endian filed added to tscannerfile class.
The value of this field is set as the same field in tentryfile class of entfile unit.
Token read and write methods converted to use change_endian field.
* ppu.pas: Increase CurrentPPILongVersion
* utils/ppuutils/ppudump.pp: Remove unneeded FPC_BIG_ENDIAN code
which was needed because tokens were previously written using a
different rule.

o enabled by default in ISO and Extended Pascal: compile-time error if not
the case in ISO mode, warning and run-time error in Extended Pascal mode
o warning enabled by default in all other modes for boolean, enumeration and
subrange integer types with ranges different from the default ones
(i.e., different from 0..255, -128..127, 0..65536, etc)
o warnings for all ordinal types can be enabled in all modes with

coalescealignskipmax to better reflex the meaning of these setting
(and the difference in meaning to e.g. constalignmax)

* extend the state of the scanner that is saved/restored when starting/stopping a token recording so that the token recorder can be started on every kind of token.

o blocks are implemented as a variation of procedure variables
o declaration of a block variable: "test: procedure(c: char) is block;"
(C equivalent: (void)(^test)(char c) )
o the compiler automatically converts procedures/functions whose address
is passed to a block parameter or assigned to a block variable into
a "block". This consists of
1) generating a block descriptor (containing the size of the "block
literal" (see below) and the signature of the invocation function
encoded as an Objective-C selector)
2) generating a wrapper function around the original funcion (with C
calling convention), that has an extra first hidden parameter
(marked as vo_is_parentfp in the compiler) whose type is a pointer
to the describing "block literal"
3) generating the "block literal", which contains a pointer to an
external variable indicating whether this block captures context or
not, some flags (see compiler/blockutl.get_block_literal_flags for
info), a pointer to the wrapper function and a pointer to the
descriptor. In the future, it will also contain captured variables.
o right now, only global procedures/functions can be converted to blocks
(because they don't require state capturing). The next steps are (Object
Pascal) methods (not Objective-C methods, because Objective-C method
procvars don't exist) and finally nested functions
o on Mac OS X, the functionality will only work on Mac OS X 10.7 and later,
because we have to use the so-called "ABI.2010.3.16" to ensure that
our blocks aren't called as variadic functions by the runtime (which
came out after the Mac OS X 10.6 release)
o while the currently implemented functionality does not require any
library support at all, there's no use enabling it on other platforms
because unless it has been confirmed to work with a blocks runtime,
there's no point in using blocks (they're just somewhat bulky procvars
right now). Enabling it on other platforms (in combination with the
GNUStep Objective-C run time), should simply be a matter of adding
the right {$linklib xxx} statement to rtl/inc/blockrtl.pp file, adding
that file to Makefile.fpc for that platform and adding that platform
to the compiler/systems.systems_blocks_supported set

o made all (non-abstract) tdef and tsym constructors virtual
o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
class
o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
class from the base classes, and initialises the c*def/c*sym classes with
them. This is done so that the llvm target will be able to derive from
the tcpu*def/sym classes without umpteen ifdefs, and it also means that
the WPO can devirtualise everything because the c* variables are only
initialised with one class type
o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
calls
