When building without systemd event support (-DLWS_WITH_SDEVENT=OFF) on
a system that has libsystemd headers installed, lib/plat/unix-systemd.c
is build in anyway.
The final libwebsockets library has then references to symbols from
libsystemd even though it won't be linked.
Resulting in the follwoing linker errros:
--
/usr/bin/ld: /usr/local/lib/libwebsockets.so: undefined reference to `sd_is_socket_inet'
/usr/bin/ld: /usr/local/lib/libwebsockets.so: undefined reference to `sd_is_socket_unix'
/usr/bin/ld: /usr/local/lib/libwebsockets.so: undefined reference to `sd_listen_fds'
--
This commit ensures that unix-system.c is only build when LWS_WITH_SDEVENT is set and
the system has libsystemd headers installed.

Linux has a sockopt flag defined by RFC5014 that informs IPv6 systems with
SLAAC config to prefer to bind the socket to a public address instead of
any temporary private address.
This patch adds a client info flag LCCSCF_IPV6_PREFER_PUBLIC_ADDR that lets
the user indicate the client socket should be prepared with the public
address binding preference.
Currently it's only implemented on Linux.
This provides an alternative esp32-specific SPI driver with ops that can be
swapped in place of the gpio bitbang one.
The pinmux info and lws gpio driver and other data in the spi bitbang
struct are used as-is by the DMA one.
New ops are provided which are able to allocate and free DMA-able memory so
the device drivers can prepare directly usable buffers. Bounce through to
DMA-able buffers is also transparently supported.
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.
VFS needs some small updates... pass in the bound fops as well as the
context fops to the member callbacks. ZIP_FOPS only cared about doing
operations on the platform / context vfs to walk the ZIP file, but other
uses are valid where we are doing operation inside the bound VFS itself.
Also, stash a cx pointer into file ops struct for convenience.
This patch checks for the env var SSLKEYLOGFILE=path, if present, then
client connection tls secrets are appended into path.vhostname.
This allows decryption of captured encrypted data for debugging purposes.
SSKEYLOGFILE=path env var method is the same as provided by Firefox and
Chrome for this purpose.
Although many of the examples must be run from the example directory as
cwd, everyone getting started probably wants to try the examples, cmake
knows how to do it, so let's enable it by default.
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.
For plugins that handle PROTOCOL_INIT, we have to iterate any PLUGINS_BUILTIN
plugins as if we had just discovered and loaded them from plugin files, so
they bind to vhosts appropriately.
Add some private helpers to keep the guts from duplication in plat.
Pick some common errno constants for the platform and provide strings for
them. Replace numeric errno logging with the new api for client.
Replace any usage of strerror() in network code with the new api. For
constrained devices, this should give a small saving on .rodata.
Leave some usages in daemonize.c and unix plat where the size isn't going
to matter.
