+ Internal linker: process unreferenced .pdata sections on x86_64-win64, restores the possibility to use GAS on win64 (which got broken by introducing SEH).

* COFF linker: postpone import section generation until unreferenced sections (and imports) are removed, and put all remaining imports into a single section. This is much more efficient than generating multiple smart-linkable import sections and immediately discarding a good half of them.

+ PECOFF targets: support more than 65535 relocations per object section, resolves #23752. DJCOFF targets: give a fatal error, since this object file format does not support extended relocations.

- Do not create any default object sections. On targets with section-based smartlink these sections remain empty and only cause linker to do useless job of removing them. The same happens when loading object files because duplicate section names are allowed at that time. On targets without smartlink they don't stay empty, but the internal assembler creates sections when required, so not creating initial sections effectively doesn't change anything.

+ Implemented two-stage removal of empty exe sections. Candidates for removal are first marked with oso_disabled flag, then actually removed. Descendants of TExeOutput that override MemPos_Start may modify list of sections pending removal. In particular, the COFF-specific .reloc section no longer has to be handled in base TExeOutput class.

* Implemented link map generation without involving TObjSection.ObjSymbolDefines, and removed the latter because it isn't used otherwise. The new approach uses CPU/memory only when map generation is requested.

- removed TCoffObjData.afteralloc, calculating MemPos there is useless because every call to afteralloc is immediately followed by call to TObjData.resetsections that resets all MemPos back to zero.

* Changed writing section symbols to use storage class COFF_SYM_LOCAL (3), this is what is used by both GCC and MSVC. Previously used COFF_SYM_SECTION (104) is accepted by GNU binutils, but only for PE targets (and silently converted to COFF_SYM_LOCAL), for DJGPP it issues warnings.
