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

Make some internal ocsp.c functions void
Only display cert usages with -help in verify
Use global bio_err, remove "BIO*err" parameter from functions
For filenames, - always means stdin (or stdout as appropriate)
Add aliases for -des/aes "wrap" ciphers.
*Remove support for IISSGC (server gated crypto)
*The undocumented OCSP -header flag is now "-header name=value"
