This eliminates the duplicated implementations of the test protocols,
except dumb-increment (which requires libuv).
This has various advantages, including bringing all the test servers
up to the same set of protocols support.
Triggered by finding a bug in server status protocol that was long
ago fixed in the plugins version.
This adds
- simple lws_urlencode()
- simple lws_urldecode()
- simple lws_sql_purify
Those expect the data to all be there and process it up until
the first '\0'.
There is also a larger opaque apis for handling POST_BODY urldecode. To
enable these, you need to give cmake -DLWS_WITH_STATEFUL_URLDECODE=1 (or
arrange any larger feature that relies on it sets that in CMakeLists.txt)
- stateful urldecode with parameter array
These have create / process / destroy semantics on a struct that maintains
decode state.
Stateful urldecode is capable of dealing with large POST data in multiple
POST_BODY callbacks cleanly, eg, file transfer by POST.
Stateful urldecode with parameter array wraps the above with a canned
callback that stores the urldecoded data and indexes them in a pointer
array matching an array of parameter names.
You may also pass it an optional callback when creating it, that will recieve
uploaded file content.
The test html is updated to support both urlencoded and multipart forms,
with some javascript to do clientside validation of an arbitrary 100KB
file size limit (there is no file size limit in the apis).

This demonstrates how to do a 303 redirect on POST and provide
the results there, in both libwebsockets-test-server and the
plugin version.

Since struct lws (wsi) now has his own context pointer,
we were able to remove the need for passing context
almost everywhere in the apis.
In turn, that means there's no real use for context being
passed to every callback; in the rare cases context is
needed user code can get it with lws_get_ctx(wsi)

This is a rewrite of the patch from Soapyman here
https://github.com/warmcat/libwebsockets/pull/363
The main changes compared to Soapyman's original patch are
- There's no new stuff in the info struct user code does any overrides
it may want to do explicitly after lws_context_create returns
- User overrides for file ops can call through (subclass) to the original
platform implementation using lws_get_fops_plat()
- A typedef is provided for plat-specific fd type
- Public helpers are provided to allow user code to be platform-independent
about file access, using the lws platform file operations underneath:
static inline lws_filefd_type
lws_plat_file_open(struct lws_plat_file_ops *fops, const char *filename,
unsigned long *filelen, int flags)
static inline int
lws_plat_file_close(struct lws_plat_file_ops *fops, lws_filefd_type fd)
static inline unsigned long
lws_plat_file_seek_cur(struct lws_plat_file_ops *fops, lws_filefd_type fd,
long offset_from_cur_pos)
static inline int
lws_plat_file_read(struct lws_plat_file_ops *fops, lws_filefd_type fd,
unsigned long *amount, unsigned char *buf, unsigned long len)
static inline int
lws_plat_file_write(struct lws_plat_file_ops *fops, lws_filefd_type fd,
unsigned long *amount, unsigned char *buf, unsigned long len)
There's example documentation and implementation in the test server.

This nukes all the oldstyle prefixes except in the compatibility code.
struct libwebsockets becomes struct lws too.
The api docs are updated accordingly as are the READMEs that mention
those apis.
