Changes since 1.15: +1 -2 lines 

Replace <sys/param.h> with <limits.h> and other less dirty headers where
possible.  Annotate <sys/param.h> lines with their current reasons.  Switch
to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc.  Change
MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where
sensible to avoid pulling in the pollution.  These are the files confirmed
through binary verification.
ok guenther, millert, doug (helped with the verification protocol)

/*
 * CERT handler for each kind of certificate:
 *
 * cert_init - initialize CERT handler.
 * crl_init - initialize CRLs, if applicable.
 * cert_get - get a certificate in internal representation from raw data.
 * cert_validate - validated a certificate, if it returns != 0 we can use it.
 * cert_insert - inserts cert into memory storage, we can retrieve with
 *               cert_obtain.
 * cert_dup - duplicate a certificate
 * cert_serialize - convert to a "serialized" form; KeyNote stays the same,
 *                  X509 is converted to the ASN1 notation.
 * cert_printable - for X509, the hex representation of the serialized form;
 *                  for KeyNote, itself.
 * cert_from_printable - the reverse of cert_printable
 * ca_count - how many CAs we have in our store (for CERT_REQ processing)
