Several new ops are planned for tls... so better to bite the bullet and
clean it out to the same level as roles + event-libs first.
Also adds a new travis target "mbedtls" and all the tests except
autobahn against mbedtls build.
You can build lws without support for ws, with -DLWS_ROLE_WS=0.
This is thanks to the role ops isolating all the ws-specific business
in the ws role.
Also retire more test apps replaced by minmal-examples.
This replaces the old test-app for echo with separate client and server
minimal versions.
The autobahn test script is made more autonomous and tests both
client and server.
There is no real need in n1, since it used in only at one place once.
Also it will prevent "variable ‘n1’ set but not used [-Werror=unused-but-set-variable]" error on build with -DLWS_MAX_SMP=N, where N > 1.
AG: also add LWS_MAP_SMP != 1 test to travis to catch this kind of thing sooner
Private header stuff specific to roles should go in the
role dir and only be included if the role is enabled for
build.
Only definitions related to lws core should go in the actual
private-libwebsockets.h
1) Remove the whole ah rxbuf and put things on to the wsi buflist
This eliminates the whole detachability thing based on ah rxbuf
state... ah can always be detached.
2) Remove h2 scratch and put it on the wsi buflist
3) Remove preamble_rx and use the wsi buflist
This was used in the case adopted sockets had already been read.
Basically there are now only three forced service scenarios
- something in buflist (and not in state LRS_DEFERRING_ACTION)
- tls layer has buffered rx
- extension has buffered rx
This is a net removal of around 400 lines of special-casing.
The closes have to complete after libuv returned to the
event loop. So make sure to catch any problem that gets
introduced where another close entry in the meanwhile is
unsafe.

This converts several of the selftests to return a status in their exit code
about whether they 'worked'.
A small bash script framework is added, with a selftest.sh in the mininmal
example dirs that support it, and a ./minimal-examples/selftests.sh script
that can be run from the build dir with no args that discovers and runs all
the selftest.sh scripts underneath.
That is also integrated into travis and the enabled tests must pass now for
travis to pass. Travis does not have a modern libuv so it can't run a
couple of tests which are nulled out if it sees it's running in travis env.
There was a small optimization for PowerPCs to pre-increment a
pointer when accessing a word, instead of post-incrementing. This
required prefacing the loop with a decrement of the pointer,
possibly pointing before the object passed. This is not compliant
with the C standard, for which decrementing a pointer before its
allocated memory is undefined. When tested on a modern PowerPC
with a modern compiler, the optimization no longer has any effect.
Due to all that, and per the recommendation of a security audit of
the zlib code by Trail of Bits and TrustInSoft, in support of the
Mozilla Foundation, this "optimization" was removed, in order to
avoid the possibility of undefined behavior.
