The goal of this patch is to make isa-l testsuite pass on s390 with
minimal changes to the library. The one and only reason isa-l does not
work on s390 at the moment is that s390 is big-endian, and isa-l
assumes little-endian at a lot of places.
There are two flavors of this: loading/storing integers from/to
memory, and overlapping structs. Loads/stores are already helpfully
wrapped by unaligned.h header, so replace the functions there with
endianness-aware variants. Solve struct member overlap by reversing
their order on big-endian.
Also, fix a couple of usages of uninitialized memory in the testsuite
(found with MemorySanitizer).
Fixes s390x part of #188.

This patch addresses one build failure and fixes several build warnings
for Arm (some for x86 too).
- Fix dynamic relocation link failure of ld.bfd 2.30 on Arm
[log] relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `xor_gen_neon' which may bind externally can not be used when making a shared object
- Add arch dependent "other_tests" to exclude x86 specific tests on Arm
[log] isa-l/erasure_code/gf_2vect_dot_prod_sse_test.c:181: undefined reference to `gf_2vect_dot_prod_sse'
- Check "fread" return value to fix gcc warnings on Arm and x86
[log] warning: ignoring return value of ‘fread’, declared with attribute warn_unused_result [-Wunused-result]
fread(in_buf, 1, in_size, in_file);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Fix issue of comparing "char" with "int" on Arm. "char" is unsigned
on Arm by default, an unsigned char will never equal to EOF(-1).
[Log] programs/igzip_cli.c:318:31: warning: comparison is always true due to limited range of data type [-Wtype-limits]
while (tmp != '\n' && tmp != EOF)
^~
- Include <stdlib.h> to several files to fix build warnings on Arm
[log] igzip/igzip_inflate_perf.c:339:5: warning: incompatible implicit declaration of built-in function ‘exit’
exit(0);

Reimplement generate_custom_hufftables.c to avoid internal dependencies. Remove
the symbol subset feature since a default incomplete huffman code is dangerous
and that functionaly is available when generating custom huffman codes.

Merge inflate.h and igzip_lib.h and rename many defines to avoid conflicts,
along with general cleanup of the new header.
