add documentation for 'enc'.

and add an nseq manpage.

The info removal code was overcomplicated, and error-prone (references being wrongly decreased).  Fixed.

  1. Added code to the memory leak detecting code to give the user the
     possibility to add information, thereby forming a traceback.

  2. Make the memory leak detecting code multithread-safe.

The idea is that we're actually dealing with two separate critical
sections, one containing the hash tables with the information, the
other containing the current memory checking mode.  Those should not
be handled with the same lock, especially since their handling overlap.
Hence, the added second lock.

Some crypto applications are now being built on Unix, so they should on VMS as well.  Not by default, however.

works on Unix and MS-DOS/Windows.  It does not under VMS, so open it
as text.

Merge some common functionality in the apps, delete
the encryption option in the pkcs7 utility (they never
did anything) and add a couple more options to pkcs7.

pages.

Update docs, change 'ca' to use the new callback parameter. Now moved key_callback
into app.c because some other utilities will use it soon.

of the openssl utility commands...

plain not working :-(

Also fix some memory leaks in the new X509_NAME code.

Fix so new app_rand code doesn't crash 'x509' and move #include so it compiles
under Win32.

certificate: currently this includes trust settings
and a "friendly name".

problem was that one of the replacement routines had not been working since
SSLeay releases.  For now the offending routine has been replaced with
non-optimised assembler.  Even so, this now gives around 95% performance
improvement for 1024 bit RSA signs.

Add a bunch of functions to simplify the creation of X509_NAME structures.

Change the X509_NAME_entry_add stuff in req/ca so it no longer uses
X509_NAME_entry_count(): passing -1 has the same effect.

don't try to detect fork()s by looking at getpid().
The reason is that threads sharing the same memory can have different
PIDs; it's inefficient to run RAND_seed each time a different thread
calls RAND_bytes.
