+ ELF linker. Works on x86_64-linux and i386-linux good enough to pass the testsuite, but still requires a lot of work in nearly all aspects. In particular, no attempt to resolve symbols from shared libs is done, everything is just treated as imports. Symbol versioning isn't supported either.

+ Extend TObjRelocation to hold untranslated platform-specific relocation types. This allows to avoid translating relocations into generic format when reading object files (which is just waste of time), and allows TObjRelocationType enumeration contain only types that are actually produced by compiler.

+ Added a flag allowing a section to be written into both .dbg and executable files. This is needed at least for ELF SHT_NOTE sections.

+ 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.

* If alignment requirement of data is bigger than alignment of the section being written to, increase section alignment to match. This mostly affects cases of non-smart linking, where wrong initial alignment used to cause hard to catch misalignment issues. It also largely obsoletes the need to supply the initial section alignment (hidden tai_section constructor,etc).
