bf35a39a15 util.poll: Include unistd.h only for epoll 
This defines close(), which is only used with epoll, hence we don't need
to include it when building in poll or select mode.

1ea488deee util.crypto: Preemptively silence 'strict-prototypes' warning 
With `gcc-12 -Wstrict-prototypes` the following warning is shown:

crypto.c:43:13: warning: function declaration isn't a prototype [-Wstrict-prototypes]
   43 | static BIO* new_memory_BIO() {

8695a72a66 util.crypto, util.jwt: Generate consistent signature sizes (via padding) 
This fixes the signature parsing and building to work correctly. Sometimes
a signature was one or two bytes too short, and needed to be padded. OpenSSL
can do this for us.

62438f482e util.crypto: Use Lua 5.2 API for predictable buffer size 
In Lua 5.3 LUAL_BUFFERSIZE is a macro computed from sizeof and is thus
not known at pre-processing time, so this does not work.

Since Lua 5.1 is no longer supported, we can use luaL_prepbuffsize()
which is available from Lua 5.2

e893bbf681 util.crypto: Use stack space buffers 
Removes assumption that LUAL_BUFFERSIZE is known at pre-processing time,
which it is not in Lua 5.3 and 5.4, where it is a computed macro based
on sizeof.

Allocation of stack space is safer and faster, no need to worry about
luaL_prepbuffer failing to allocate memory and skipping free()

6a64363e78 util-src: Add new utility header managed_pointer.h

managed C alloc/free APIs.

dabdfc91be util.table: Fix inaccurate comment 
Probably a duplicate of the comment next to Lmove, recorded by mistake

Lpack can probably be removed at some point in the near future once we
are confident it is not used anywhere.

b1c7b93139 util.hashes: Revert to HMAC() convenience function 
Reverts some of 1e41dd0f8353

Seems HMAC() isn't deprecated after all? Must have been at some point
according to #1589

Twice as fast for some reason.

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.

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+.
