Merge pull request #2439 from senhuang42/skippable_frame_api 
Generate skippable frame API

dd1a7e41ee Add ifndef guards for _LARGEFILE_SOURCE and _LARGEFILE64_SOURCE 
This ensures the symbols aren't redefined, which would result in a compiler
error.

I was getting redefined symbols for _LARGEFILE64_SOURCE when building for
32-bit x86 Linux on an older CentOS release in a CI environment. With this
change, I'm able to compile the single file library in this environment.

Closes #2443.

a7cb4af573 added emphasis on the alignment condition of workspace 
and made it a programming mistake (`assert()`)
rather than a runtime error.

ae85676d44 Fix alignment of scratchBuffer in HUF_compressWeights() 
The scratch buffer must be 4-byte aligned. This causes test failures in
32-bit systems, where the stack isn't aligned.

Fixes Issue #2428.

c56723ab03 replace final links by direct copy 
link can behave slightly differently from real binaries,
breaking a few scripts relying on "real binary" assumption.

1bbcf07bd5 [huf_compress] Refactor and comment HUF_buildCTable() 
Comment and refactor `HUF_buildCTable()` and the helper functions
it calls as I read and understand the code. Hopefully this refactor
makes the code a bit more clear.
