Partial addition of 'const' to all interfaces above the (micro)kernels. (#625)

Details:
- Added 'const' qualifier to applicable function arguments wherever the
  the pointed-to object is not internally modified. This change affects 
  all interfaces that reside above the level of the (micro)kernels.
- Typecast certain function return values to discard 'const' qualifier.
- Removed 'restrict' from various arguments, including cntx_t*,
  auxinfo_t*, rntm_t*, thrinfo_t*, mem_t*, and others
- Removed parts of some APIs, such as bli_cntx_*(), due to limited use.
- Merged some variable declarations with their corresponding 
  initialization statements.
- Whitespace changes.
