SEQUENCE and CHOICE fixes, plus security terms descriptions

* Finished CANONICAL-XER implementation by adding SET and SET OF
canonical ordering support.
......@@ -7,6 +7,12 @@
* Removed C99'izm from the x509dump, now understood by older compilers.
* Enhanced UTF8String constraint validation, now it checks
for the minimal encoding length; API of UTF8String_length() changed.
* Fixed SEQUENCE dealing with premature termination of the
optionals-laden indefinite length structure. The code was previously
refusing to parse such structures.
* Fixed CHOICE code spin when indefinite length structures appear
in the extensions (Severity: medium, Security impact: medium).

=== Bug importance disclosure terms ===
SEVERITY.
This term applies to the frequence the particular construct is used
in the real world. The higher the frequency, the more chances of triggering
this bug.
low: The ASN.1 specifications which could trigger
this kind of bug are not widespread.
medium: The particular ASN.1 construct is used quite often,
so the chance of triggering an error is considerable.
high: This fix is considered urgent, or the particular ASN.1
construct triggering this bug is in wide use.
SECURITY IMPACT.
This term applies to the amount of potential damage a bug exploitation
could cause.
low: The local exploitation is unlikely; the remote exploitation
is impossible.
medium: The remote exploitation is possible when a particular ASN.1
construct is being used. If possible, only hard failure, spin
or memory leak are the possible outcome: no shellcode
injection could possibly be carried by the attack.
high: The remote shellcode injection is possible, or the bug is
otherwise remotely exploitable for most specifications.
