+ 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.

- 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.
