Also max protocols to 5 (overridable by configure) and max extensions
from 10 to 3 by default (also overridable by configure).
wsi is down to 608 on x86_64 with this.

As reported here
http://libwebsockets.org/trac/ticket/11
the code for connection storm handling had rotted, fds[0] is no longer
always related to the listen socket when serving.
This patch updates it to determine the listen socket correctly to stop
infinite recursion here.

Now we enforce nonblocking everywhere, hopefully properly,
this rx timeout stuff shouldn't be needed.

*** This patch changes an API all apps use ***
Context creation parameters are getting a bit out of control, this
patch creates a struct to contain them.
All the test apps are updated accordingly.

A new protocol member is defined that controls the size of rx
buffer allocation per connection. For compatibility 0 size
allocates 4096, but you should adapt your protocol definition
array in the user code to declare an appropriate value.
See the changelog for more detail.
The advantage is the rx frame buffer size is now tailored to
what is expected from the protocol, rather than being fixed
to a default of 4096. If your protocol only sends frames of
a dozen bytes this allows you to only allocate an rx frame
buffer of the same size.
For example the per-connection allocation (excluding headers)
for the test server fell from ~4500 to < 750 bytes with this.

This gets rid of the stack buffer while serving files, and the
PATH_MAX char array that used to hold the filepath in the wsi.
It holds an extra file descriptor open while serving the file,
however it attempts to stuff the socket with as much of the
file as it can take. For files of a few KB, that typically
completes (without blocking) in the call to
libwebsockets_serve_http_file() and then closes the file
descriptor before returning.

This reduces the size of struct libwebscocket from 4840 to 4552
on x86_64
There are also big benefits on malloc pool fragmentation and
allocation, the header allocations only exist between the first
peer communication and websocket connection establishment for
both server and client.

- Small Size: 20-100kB
- Runtime Memory: 1-36kB
- 20X smaller than OpenSSL
So far only tested on Linux.
Note that this requires a bugfix in cyassl, otherwise it will crash. Pull request has been made to the official repos, in the meantime the following repos can be used: git://github.com/JoakimSoderberg/cyassl.git
- For some reason the "extern int pid_daemon" usage in libwebsockets.c would cause an "undefined symbols" linker error for the test-apps. This only happens with the CMake project, not the normal Makefiles. I have no clue why this is. Fixed it by getting the pid via a function instead.
- Added test-server-extpoll
- Renamed the library from libwebsocket -> libwebsockets
- Finalized CMake support (tested on windows only so far).
- Uses a generated lws_config.h that is included in
private-libwebsocket to pass defines, only used if CMAKE_BUILD is set.
- Support for SSL on Windows.
- Initial support for CyaSSL replacement of OpenSSL (This has been added
to my older CMake-fork but haven't been tested on this version yet).
- Fixed windows build (see below for details).
- Fixed at least the 32-bit Debug build for the existing Visual Studio
Project. (Not to keen fixing all the others when we have CMake support
anyway (which can generate much better project files)...)
- BUGFIXES:
- handshake.c
- used C99 definition of handshake_0405 function
- libwebsocket.c
- syslog not available on windows, put in ifdefs.
- Fixed previous known crash bug on Windows where WSAPoll in
Ws2_32.dll would not be present, causing the poll function pointer
being set to NULL.
- Uninitialized variable context->listen_service_extraseen would
result in stack overflow because of infinite recursion. Fixed by
initializing in libwebsocket_create_context
- SO_REUSADDR means something different on Windows compared to Unix.
- Setting a socket to nonblocking is done differently on Windows.
(This should probably broken out into a helper function instead)
- lwsl_emit_syslog -> lwsl_emit_stderr on Windows.
- private-libwebsocket.h
- PATH_MAX is not available on Windows, define as MAX_PATH
- Always define LWS_NO_DAEMONIZE on windows.
- Don't define lws_latency as inline that does nothing. inline is not
support by the Microsoft compiler, replaced with an empty define
instead. (It's __inline in MSVC)
- server.c
- Fixed nonblock call on windows
- test-ping.c
- Don't use C99 features (Microsoft compiler does not support it).
- Move non-win32 headers into ifdefs.
- Skip use of sighandler on Windows.
- test-server.c
- ifdef syslog parts on Windows.
This exposes the library version and git head hash it was built from
into LWS_LIBRARY_VERSION and LWS_BUILD_HASH.
These are combined into a version string that's both printed as a
notice log by the library and made available to the app using a new
api lws_get_library_version(). The version looks like
1.1 178d78c
