* FUNCTION: pkix_pl_oidBytes2Ascii

*
* Converts the DER encoding of an OID pointed to by "secItem" to an ASCII
* representation and stores it at "pAscii". The ASCII representation is
* guaranteed to end with a NUL character. The input SECItem must contain
* non-NULL data and must have a positive length.

* Example: the six bytes {2a 86 48 86 f7 0d} represent the
* four integer tokens {1, 2, 840, 113549}, which we will convert
* into ASCII yielding "1.2.840.113549"
*
* The return value "pAscii" is not reference-counted and will need to
* be freed with PKIX_PL_Free.
*
* PARAMETERS
* "secItem"
* Address of SECItem which contains bytes and length of DER encoding.
* Must be non-NULL.
* "pAscii"
* Address where object pointer will be stored. Must be non-NULL.
* "plContext"
* Platform-specific context pointer.
* THREAD SAFETY:
* Thread Safe (see Thread Safety Definitions in Programmer's Guide)
* RETURNS:
* Returns NULL if the function succeeds.
* Returns an OID Error if the function fails in a non-fatal way.
* Returns a Fatal Error if the function fails in an unrecoverable way.

* FUNCTION: pkix_UTF16_to_EscASCII
* DESCRIPTION:
*
* Converts array of bytes pointed to by "utf16String" with length of
* "utf16Length" (which must be even) into a freshly allocated Escaped ASCII
* string and stores a pointer to that string at "pDest" and stores the
* string's length at "pLength". The Escaped ASCII string's length does not
* include the final NUL character. The caller is responsible for freeing
* "pDest" using PKIX_PL_Free. If "debug" is set, uses EscASCII_Debug
* encoding.
*
* PARAMETERS:
* "utf16String"
* Address of array of bytes representing data source. Must be non-NULL.
* "utf16Length"
* Length of data source. Must be even.
* "debug"
* Boolean value indicating whether debug mode is desired.
* "pDest"
* Address where data will be stored. Must be non-NULL.
* "pLength"
* Address where data length will be stored. Must be non-NULL.
* "plContext"
* Platform-specific context pointer.
* THREAD SAFETY:
* Thread Safe (see Thread Safety Definitions in Programmer's Guide)
* RETURNS:
* Returns NULL if the function succeeds.
* Returns a String Error if the function fails in a non-fatal way.
* Returns a Fatal Error if the function fails in an unrecoverable way.

* FUNCTION: pkix_pl_PrimHashTable_Remove
* DESCRIPTION:
*
* Removes any objects with the key pointed to by "key" and hashCode value
* equal to "hashCode" from the PrimHashtable pointed to by "ht", using the
* function pointed to by "keyComp" to compare keys, and stores the object's
* value at "pResult". Assumes "key" is a PKIX_UInt32 or a PKIX_PL_Object.
* This function sets "pResult" to NULL if the key is not in the hashtable.
*
* PARAMETERS:
* "ht"
* Address of PrimHashtable to remove object. Must be non-NULL.
* "key"
* Address of key for lookup. Typically a PKIX_UInt32 or PKIX_PL_Object.
* Must be non-NULL.
* "value"
* Address of Object to be added to PrimHashtable. Must be non-NULL.
* "hashCode"
* Hashcode value of the key.
* "keyComp"
* Address of function used to determine if two keys are equal.
* If NULL, pkix_pl_KeyComparator_Default is used.
* "pResult"
* Address where value will be stored. Must be non-NULL.
* "plContext"
* Platform-specific context pointer.
* THREAD SAFETY:
* Not Thread Safe - assumes exclusive access to "ht"
* (see Thread Safety Definitions in Programmer's Guide)
* RETURNS:
* Returns NULL if the function succeeds.
* Returns a HashTable Error if the function fails in a non-fatal way.
* Returns a Fatal Error if the function fails in an unrecoverable way.

* FUNCTION: pkix_pl_CRL_ToString_Helper
* DESCRIPTION:
*
* Helper function that creates a string representation of the CRL pointed
* to by "crl" and stores it at "pString".
*
* PARAMETERS
* "crl"
* Address of CRL whose string representation is desired.
* Must be non-NULL.
* "pString"
* Address where object pointer will be stored. Must be non-NULL.
* "plContext"
* Platform-specific context pointer.
* THREAD SAFETY:
* Thread Safe (see Thread Safety Definitions in Programmer's Guide)
* RETURNS:
* Returns NULL if the function succeeds.
* Returns a CRL Error if the function fails in a non-fatal way.
* Returns a Fatal Error if the function fails in an unrecoverable way.
