efb3cfcbc7 - don't write the default unit code section in the beginning of each asm file, 
when using {$hugecode on}, to avoid bogus nasm warnings

597f110eb9 + added support for units with code larger than 64kb in the far code i8086 
memory models. Enabled by the new directive {$hugecode on}. The directive is
  ignored in the near code memory models. When enabled, it forces each procedure
  to be in a separate segment and disables mixing near and far procedures (so
  'near' and {$F-} are ignored in this mode). Note that {$hugecode on} does not
  count as a different memory model, because you can freely link modules (units)
  compiled with {$hugecode on} and {$hugecode off}.

9c54cdc85d * x86: Cleaned out addr_far,addr_far_ref used to encode far calls/jumps. NASM (and FPC x86 assembler based on it) already have opsize=S_FAR for this purpose.

f69e6ec389 * Some fixes to NASM writer: 
* Correctly output names of sec_user sections and sec_threadvar on Windows targets
  * Use ALIGNB directive to align without warnings in bss and alike sections.
  * Do not output 'begin/end asmlist x' for empty asmlists.

c00b56ae49 * added the -w-orphan-labels parameter to all tasminfo instances for nasm. 
The -w-oprhan-labels option prevents the 'label alone on a line without a
  colon might be in error' warning.

39c54bf077 * handle ait_varloc in the nasm writer. This allows compiling the system unit 
for i8086 with regvars and -sr for debugging purposes.

2d45ea43af * use the 'wait' prefix (on the same line as the instruction), instead of 
'db 09bh' (on the previous line) for the fwait prefixed 8087 instructions in
  the nasm assembly output, because it looks prettier this way :)

0020a2ed10 + when targeting the i8087, emit FWAIT prefix manually for the 8087 instructions 
that require it in the NASM asm writer, since NASM doesn't do it itself.

661e11ecb8 * on i8086 added section .fpc to the group 'dgroup'. This fixes a bug that caused the bss section to not be left out from the executable in tiny model, which caused, ironically, tiny model executables to be larger than the small model executables

511b1f37c1 * write the segment of aitconst_farptr on a separate line to avoid long symbol truncation, due to line length limit; this fixes compilation of sysutils in the medium memory model

14cfe770a4 * replaced most (if not all) remaining fields/parameters in the compiler 
that deal with paths/filenames with TPathStr (= ansistring) to prevent
    cutting off long paths (no change in speed when compiling the compiler,
    1% extra memory usage)

ac43eb9b70 + generic implementation of ReplaceForbiddenAsmSymbolChars() instead 
of the AVR-specific ifdef'ed variant
   o since the only special character we use in mangled names on all platforms
     is $, added a new field to tasminfo called "dollarsign" that holds the
     character $'s should be replaced with (if it doesn't have to be replaced,
     leave it at $)

4c21beb48e win64 unwinding, misc fixes:
