- fixed two similar potential memory leaks:
  1) rsa_priv_get(). If fclose() failed, NULL was returned, but RSA that 
   had been allocated earlier was not RSA_free():d.
  2) cert_load(). If fclose() failed, NULL was returned, but X509 that had 
  been allocated earlier was not X509_free():d.

- declared pass_cb() as static

- configure.ac: $mandir defaults to /usr/local/man on Solaris and 
  /usr/share/man on Linux. $prefix defaults to empty value.
- allow symbolic links in /dev/urandom path because at least the
  unofficial /dev/urandom patch for Solaris 8 creates /dev/urandom
  as a symbolic link
- officially declare the pamrsakp to be unportable across
  the wonderful world of shell scripts. It unashamedly uses 
  exotic features like '!' to express negation and expects things
  like 'echo -n' to work. I HATE SHELL PROGRAMMING SINCE NOTHING
  IS PORTABLE.

- support for passphrase encrypted RSA private keys (thanks to Niko Tyni for suggestion)
