Implemented UAL syntax support in the ARM assembler reader. Can be toggled with a field for now, but not implemented yet. Still using pre-UAL syntax for now.

* ELF linker: track relocation style (REL or RELA) of each input section and use it instead of global default on MIPS targets. This fixes internal linking of tests/test/units/system/tres*.pp.

* It is incorrect to use var_align() in linker code: it depends on current_settings.alignment, which is valid only while compiling, not while linking. Replaced with size_2_align().

+ Internal linker: base support for sections that aren't referenced but must be linked if section referenced by them is linked (like win64 .pdata). Actual handling is still to be implemented in descendant classes.

* 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.

- TObjData.sectiontype2options: removed oso_keep flags. They don't have any effect here because this function is used only during assembling, and oso_keep cannot be represented in object files and therefore gets lost before linking.

* Don't calculate data position of each object section. Instead, write out a copy of exesection's memory image, i.e. every objsection is placed at the same offset from its owning exesection both on disk and in memory. This approach is simpler and works regardless of alignment requirements, while existing one could work only if SectionDataAlign<=SectionMemAlign.
