957503436e http: mounts: LWSMPRO_NO_MOUNT
Provide a way to apply exception mount urls that exist on top of a larger
mount, but provide an exception which enforces the url to not be serviced
by the mount code, but by whatever dynamic handler is in place.

2de67dd0ae file_ops: vfs: support prefix matches and use of bound ops members
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.

cf2dbdc6a0 vhost: create multiple listen sockets per AF
On some platforms AF_INET and AF_INET6 must be listened for on separate
sockets.  Adapt the vhost server creation code to use the new support for
multiple listen sockets per vhost to create up to two listen sockets for
AF_INET and AF_INET6.

It refactors how the decision about the AF is made and propagated so
there's only one place for it.

6163c96727 vhost: allow multiple listen sockets
Some platforms need two sockets with AF_INET and AF_INET6 to listen to both
protocols.

This patch changes the single listen socket each vhost could previously
handle to become an lws_dll2 and adapts the related code to handle them as
a linked-list rather than as a singleton.

The next patch adapts the listen / server code to create multiple listen
wsi for vhosts listening on multiple ip protocols.

3f4623bb36 lws_metrics
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.

c9731c5f17 type comparisons: fixes
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.

0ceba15d9c lws_lifecycle
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.

d330dbd76a wsi: unify base wsi creation function
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

3549a94ce6 roles: compress role ops structs
role ops are usually only sparsely filled, there are currently 20
function pointers but several roles only fill in two.  No single
role has more than 14 of the ops.  On a 32/64 bit build this part
of the ops struct takes a fixed 80 / 160 bytes then.

First reduce the type of the callback reason part from uint16_t to
uint8_t, this saves 12 bytes unconditionally.

Change to a separate function pointer array with a nybble index
array, it costs 10 bytes for the index and a pointer to the
separate array, for 32-bit the cost is

2 + (4 x ops_used)

and for 64-bit

6 + (8 x ops_used)

for 2 x ops_used it means 32-bit: 10 vs 80 / 64-bit: 22 vs 160

For a typical system with h1 (9), h2 (14), listen (2), netlink (2),
pipe (1), raw_skt (3), ws (12), == 43 ops_used out of 140, it means
the .rodata for this reduced from 32-bit: 560 -> 174 (386 byte
saving) and 64-bit: 1120 -> 350 (770 byte saving)

This doesn't account for the changed function ops calling code, two
ways were tried, a preprocessor macro and explicit functions

For an x86_64 gcc 10 build with most options, release mode,
.text + .rodata

before patch:          553282
accessor macro:        552714 (568 byte saving)
accessor functions:    553674 (392 bytes worse than without patch)

therefore we went with the macros

c6c7ab2b44 event libs: default to building as dynamically loaded plugins
Event lib support as it has been isn't scaling well, at the low level
libevent and libev headers have a namespace conflict so they can't
both be built into the same image, and at the distro level, binding
all the event libs to libwebsockets.so makes a bloaty situation for
packaging, lws will drag in all the event libs every time.

This patch implements the plan discussed here

https://github.com/warmcat/libwebsockets/issues/1980

and refactors the event lib support so they are built into isolated
plugins and bound at runtime according to what the application says
it wants to use.  The event lib plugins can be packaged individually
so that only the needed sets of support are installed (perhaps none
of them if the user code is OK with the default poll() loop).  And
dependent user code can mark the specific event loop plugin package
as required so pieces are added as needed.

The eventlib-foreign example is also refactored to build the selected
lib support isolated.

A readme is added detailing the changes and how to use them.
