The big apps cleanup broke the windows build. This commit
fixes some miscellaneous issues so that it builds again.

There were a set of includes in dtls1.h which are now redundant due to the
libssl opaque work. This commit removes those includes, which also has the
effect of resolving one issue preventing building on windows (i.e. the
include of winsock.h)

Many functions had a BIO* parameter, and it was always called
with bio_err.  Remove the param and just use bio_err.

ANSI C, and OpenSSL's malloc wrapper do this, also.

Remove ERR_[gs]et_implementation as they were not undocumented and
useless (the data structure was opaque).

Halve the number of lock/unlock calls in almost all ERR_
functions by letting the caller of get_hash or int_thread_set
able to lock.  Very useful when looping, such as adding errors,
or when getting the hash and immediately doing a lookup on it.

We have an increasing number of function declarations starting with

The previous check assumed that the variables for each test app, ending
with TEST would be indication enough.  Experience showed that this isn't
the best way.  Instead, simply look for the EXE variable in test/Makefile.

A variable declaration got dropped during a merge.
And if a compiler inlines strcmp() and you put a strcmp in an

This is merges the old "rsalz-monolith" branch over to master.  The biggest
change is that option parsing switch from cascasding 'else if strcmp("-foo")'
to a utility routine and somethin akin to getopt.  Also, an error in the
command line no longer prints the full summary; use -help (or --help :)
for that.  There have been many other changes and code-cleanup, see
bullet list below.

Special thanks to Matt for the long and detailed code review.
