mbedtls seemed to realize that they went overboard with the privacy stuff
on v3.0 and removed some of it. Introduce support for those members that
are only private on exactly v3.0 and unprotected before and after.
continue here makes no difference than using break, but continue gets us a
pointless complaint "statement continue does not have any effect" and break
does not.
Adapt mbedtls support for compatibility with v3, while maintaining
compatibility with v2.
Notice v3 has removed the ability to encrypt with pubkey and
decrypt with privkey. Openssl still has it, atm with v3 these
fall back to encrypt with privkey and decrypt with pubkey.

These functions can return 0 code but still store NULL in result, if no matching group or username found.
Also the buffer of 64 size could be too small to store all string fields in result.
Otherwise sai is sometimes failing to get the correct process exit code
spawn: use WEXITSTATUS macro
On openbsd at least, the process retcode isn't in the low 8 bits, but must
be recovered using the official macro.
There are a few build options that are trying to keep and report
various statistics
- DETAILED_LATENCY
- SERVER_STATUS
- WITH_STATS
remove all those and establish a generic rplacement, lws_metrics.
lws_metrics makes its stats available via an lws_system ops function
pointer that the user code can set.
Openmetrics export is supported, for, eg, prometheus scraping.
Also prioritize LD_LIBRARY_PATH check for plugins first
Iterate through paths in LD_LIBRARY_PATH in order
Warn on failed plugins init but continue protocol init
This is a huge patch that should be a global NOP.
For unix type platforms it enables -Wconversion to issue warnings (-> error)
for all automatic casts that seem less than ideal but are normally concealed
by the toolchain.
This is things like passing an int to a size_t argument. Once enabled, I
went through all args on my default build (which build most things) and
tried to make the removed default cast explicit.
With that approach it neither change nor bloat the code, since it compiles
to whatever it was doing before, just with the casts made explicit... in a
few cases I changed some length args from int to size_t but largely left
the causes alone.
From now on, new code that is relying on less than ideal casting
will complain and nudge me to improve it by warnings.
This adds some new objects and helpers for keeping and logging
info on grouped allocations, a group is, eg, SS handles or client
wsis.
Allocated objects get a context-unique "tag" string intended to replace
%p / wsi pointers etc. Pointers quickly become confusing when
allocations are freed and reused, the tag string won't repeat
until you produce 2^64 objects in a context.
In addition the tag string documents the object group, with prefixes
like "wsi-" or "vh-" and contain object-specific additional
information like the vhost name, address / port or the role of the wsi.
At creation time the lws code can use a format string and args
to add whatever group-specific info makes sense, eg, a wsi bound
to a secure stream can also append the guid of the secure stream,
it's copied into the new object tag and so is still available
cleanly after the stream is destroyed if the wsi outlives it.
A few different places want to create wsis and basically repeat their
own versions of the flow. Let's unify it into one helper in wsi.c
Also require the context lock held (this only impacts LWS_MAX_SMP > 1)
C++ APIs wrapping SS client
These are intended to provide an experimental protocol-independent c++
api even more abstracted than secure streams, along the lines of
"wget -Omyfile https://example.com/thing"
WIP
CTest does not directly support daemon spawn as part of the test flow,
we have to specify it as a "fixture" dependency and then hack up daemonization
in a shellscript... this last part unfortunately limits its ability to run to
unix type platforms.
On those though, if the PROXY_API cmake option is enabled, the ctest flow will
spawn the proxy and run lws-minimal-secure-strems-client against it
