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

Tickets closed:
RT3515: Use 3DES in pkcs12 if built with no-rc2
RT1766: s_client -reconnect and -starttls broke
RT2932: Catch write errors
RT2604: port should be 'unsigned short'
RT2983: total_bytes undeclared #ifdef RENEG
RT1523: Add -nocert to fix output in x509 app
RT3508: Remove unused variable introduced by b09eb24
RT3511: doc fix; req default serial is random

RT2119,3407: Updated to dgst.pod
RT2379: Additional typo fix
RT2693: Extra include of string.h
RT2880: HFS is case-insensitive filenames
RT3246: req command prints version number wrong

Other changes; incompatibilities marked with *:
Add SCSV support
Add -misalign to speed command
Make dhparam, dsaparam, ecparam, x509 output C in proper style
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"
*Documented the OCSP -header flag

OPENSSL_NO_xxx cleanup: SHA

Remove support for SHA0 and DSS0 (they were broken), and remove
the ability to attempt to build without SHA (it didn't work).
For simplicity, remove the option of not building various SHA algorithms;
you could argue that SHA_224/256/384/512 should be kept, since they're
like crypto algorithms, but I decided to go the other way.
So these options are gone:
GENUINE_DSA OPENSSL_NO_SHA0
OPENSSL_NO_SHA OPENSSL_NO_SHA1
OPENSSL_NO_SHA224 OPENSSL_NO_SHA256
OPENSSL_NO_SHA384 OPENSSL_NO_SHA512
