[ptxdist] [PATCH v2 1/2] libwebsockets: new package

[Ian Abbott <abbotti@mev.co.uk>]

Includes the C library from the Libwebsockets (LWS) project, with
options for adding TLS (SSL) support, and options the adding various
event loop libraries that are dynamically loaded as plug-ins.

Signed-off-by: Ian Abbott <abbotti@mev.co.uk>
---
v2: Get sources from github instead of libwebsockets.org's own git
server due to unreliable, on-the-fly generated tarballs from the latter.
