ae14dc1220 util.hashes: Expose sha224 and sha384 HMAC functions 
For completeness and consistency with set of plain hash functions

54f8ca81f4 util.hashes: Refactor HMAC bindings (fixes #1589) 
HMAC() is deprecated

As with the regular hash functions, macros like this make it awkward to
apply static analysis and code formatting.

d690f1502a util.hashes: Refactor hash functions to use OpenSSL EVP methods (fix #1698) 
MD5() is deprecated, but EVP_md5() is not.

Functions in macros like this make it awkward to apply static analysis
and code formatting.

787835d693 util.strbitop: Reduce scope of functions 
Equivalent to 'local' in Lua, these functions are exported via the
luaopen_ function, which is the only one needing to be visible outside
of the file.

Pointed out by Link Mauve at some point, but there wasn't really any
rush here.

26605b5197 util.table: Backport table.move() from Lua 5.4 
One difference is that 5.4 accepts "table-like" values (for this and other
table.*() functions), but that would require additional backporting work.

43351d2b54 Spelling: Fix various spelling mistakes (thanks timeless) 
Words, sometimes I wonder how they even work

Maybe I missed something.

fe56effa55 util.struct: Import Roberto 'struct' library v0.3 
Downloaded from http://www.inf.puc-rio.br/~roberto/struct/

This is for compatibility with Lua 5.2 (and 5.1). Eventually we can replace
this with string.pack/string.unpack which are available in 5.3+.

9b8a54345f util.strbitop: Remove redundant init function 
When you have 3 almost identical functions, you tend to edit one and
then copypaste. Forgot to remove this line from the other two.

da8eca639a util.strbitop: Create buffer in the correct size (optimization) 
This avoids dynamically growing the buffer as Lua does when luaL_addchar
is used, thus saving on realloc calls.

625ec0a93f util-src: Use the luaL_pushfail API added in Lua 5.4 to highlight all failure conditions 
Actually just an alias of pushnil, but it does make it more obvious
where the failure conditions are, which is good for readability.

8055c8f7d7 util.pposix,signal: Pass around various OS numbers as integers [Lua 5.3] 
Passing around PIDs, UIDs etc as integers makes it more sane in Lua 5.3.
Getting 1234.0 as PID is silly. Shouldn't change any behavior as these
are all integers on the C side and the integral floats are accepted as
integers when passed back from Lua into C.
