Fix main build breakage.

A variable declaration got dropped during a merge.
And if a compiler inlines strcmp() and you put a strcmp in an
assert message, the resultant stringification exceeds ANSI string
limits.

Big apps cleanup (option-parsing, etc)

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.

TEMPORARY:
For now, comment out CRYPTO_mem_leaks() at end of main

Add -no_alt_chains option to apps to implement the new
X509_V_FLAG_NO_ALT_CHAINS flag. Using this option means that when building
certificate chains, the first chain found will be the one used. Without this
flag, if the first chain found is not trusted then we will keep looking to
see if we can build an alternative chain instead.
