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
RT1325,2973: Add more extensions to c_rehash
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
