The file types.h has long been misnamed and overlaps with
functionality in the test helper routines.

The gf_{2-6}vect_dot_prod tests were kept in other_tests since the 5,6vect
functions were not strictly called by the higher level ec_encode_data() and
needed independent testing. As this has now changed the extra tests can be
removed as redundant.

Added AVX512 optimized functions to calculate the
GF(2^8) vector dot product with 5 and 6 outputs
at a time. Also added GF(2^8) vector multiply
AVX512 optimized functions with 5 and 6 accumulate.

1.Replace below erasure code interfaces to arm neon interface by mbin_interface function.
ec_encode_data
gf_vect_mul
gf_vect_dot_prod
gf_vect_mad
ec_encode_data_update
2.Utilise arm neon instrution to accelerate GF(2^8) set compute by 128bit registor.

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);

Remove gf_vect_mad_perf.c as it is architecture specific and does not provide
useful information in its current format.

Add a program calculating some of the exact conditions where gf_gen_rs_matrix
works, add comments stating these bounds to gf_gen_rs_matrix, and fix erasure
code test that violates the bounds.

Allows configure to again build in an external directory. When building ISAL in
an external path, assembler or compiler needs relative include paths.

- Includes gf_nvect_dot_prod, gf_nvect_mad functions
- Change ec multibinary to use common macros
- Autoconf checks for nasm or yasm support and picks if available
- Leave out compile of any avx512 code if assembler not available
