On unpacking, reinstate any p_align values that packing reduced to
page size. Ensures a round-trip pack and unpack is bit-equivalent
to the original input.

Extend unit tests to include ia32, x64, and mips32.
Recreate test data for arm32 and arm64. Generate new test data for
ia32, x64, and mips32.

Having p_align > page_size leads to the situation when striping
packed executables results in unnecessary p_vaddr adjustments.
And it also may result (with probability 1 - 1/sizeof(uintptr_t)) in
misaligned segments following .dynstr

According to runs on /system/lib there using
unsigned leb128 does not save us any additional
space. In order to keep packing as simple as
possible switch to using signed leb128 for
everything.

Removes:
- src/run_length_encoder.h
artifact of the original packing tool, not used here
- test_data/generate_elf_file_unittest_relocs.sh
- test_data/generate_elf_file_unittest_relocs.py
test data generation for chromium/gyp, not usable here
- README.TXT
because it is now almost entirely outdated

1. One binary for all architectures
2. Generalize (and slightly improve) compression
2.1 works on all relocation types (rela?.dyn section only so far)
2.2 Uses same format to encode ElfW(Rel) as well as ElfW(Rela) tables
