+ Added codes of dynamic relocations to TElfTarget; since most targets use similar dynamic relocation model differing only in code values, this will allow to do majority of handling in the base class.

* Fixed a bug introduced in r23077: relative_reloc_count must be increased only once per GOT entry, not every time a relocation to that entry is seen.

- Removed generic implementation of TObjData.sectionname, its existence is useless because it is completely overridden by all TObjData descendants.

+ 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.

* When writing section names of .o files, let sh_name of sections with relocations point into names of corresponding relocation sections past the .rel/.rela prefix. In case of smartlinked sections this saves almost half of .shstrtab section size.
