check for default protocol rx buf limit
This fixes
http://libwebsockets.org/trac/ticket/13
When using the default rx protocol buffer, the check is
performed against 0 not the default length. That's the
case both in client and server code...
There's no problem if you actually give a max frame size
in the protocol definition.

Fixed DLL compilation on Windows for CMake.
- Define LWS_DLL and LWS_INTERNAL when websockets_shared is compiled.
- The websocket_shared target compiles to websocket.lib / websocket.dll
(websocket.lib contains the exported functions for websocket.dll, and is
the file that is linked to when a program wants to use the dll)
- The websocket target compiles to websocket_static.lib on windows.
- Replaced any "extern" with "LWS_EXTERN" on libwebsockets.h for proper
DLL function exports.
- Created a LIB_LIST with all the libwebsocket dependencies, instead of
multiple calls to target_link_libraries, only one call is made for both
the static and shared library version. This makes it easy to add other
variants if wanted in the future.
- Added ZLIB as a dependency for the libs, so that the build order will be
correct at all times.
- Added a dependency for the websockets lib to the test apps, so it is
built before them.
- Fixed the test-server-extpoll app to include the emulated_poll, and link
to winsock on Windows.
- Removed the global export of libwebsocket_internal_extensions, and added
a function libwebsocket_get_internal_extensions() that returns it
instead. Using the global would not work with the DLL export on Windows.

fix ssl reject path for freeing header allocation
If the SSL connection failed before the headers came, we were not
dealing with deallocating the header malloc. This takes care of it.
Using CyaSSL, we are then valgrind-clean for ssl client and server.
With OpenSSL, there is 88 bytes lost at init that never changes or
gets recovered. AFAIK there's nothing to do about that.
OpenSSL also blows these during operation

replace per header mallocs with single malloc 3 level struct
This big patch replaces the malloc / realloc per header
approach used until now with a single three-level struct
that gets malloc'd during the header union phase and freed
in one go when we transition to a different union phase.
It's more expensive in that we malloc a bit more than 4Kbytes,
but it's a lot cheaper in terms of malloc, frees, heap fragmentation,
no reallocs, nothing to configure. It also moves from arrays of
pointers (8 bytes on x86_64) to unsigned short offsets into the
data array, (2 bytes on all platforms).
The 3-level thing is all in one struct
- array indexed by the header enum, pointing to first "fragment" index
(ie, header type to fragment lookup, or 0 for none)
- array of fragments indexes, enough for 2 x the number of known headers
(fragment array... note that fragments can point to a "next"
fragment if the same header is spread across multiple entries)
- linear char array where the known header payload gets written
(fragments point into null-terminated strings stored in here,
only the known header content is stored)
http headers can legally be split over multiple headers of the same
name which should be concatenated. This scheme does not linearly
conatenate them but uses a linked list in the fragment structs to
link them. There are apis to get the total length and copy out a
linear, concatenated version to a buffer.

correct test client to close synchronously with last send
Noticed previously the test client lifetime is decoupled from
the actual send activity. With SSL if the connection starts but
there is a period of SSL-layer "blocking" (actually fail-and-retry)
the mirror lifetime could be exhausted before the connection really
completed, making it stall after it was then closed.
This corrects that so connection lifetime management is done in the
send callback.

remove fixed rx buffer allow definition per protocol
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.

remove need for filepath buffer on http file serve
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.
