Our asn1_print, like OpenSSL's, just knows how to parse and dump DER.
Ours can attempt to decode OCTET STRING and IMPLICIT-tagged constructed
values as DER, which is very useful.
But _now_ it's even better. Now it knows about all types exported from
all ASN.1 modules in `lib/asn1/` in Heimdal, and if told to print as
some type, it will use the new printing interface to print JSON-like
representations of values:
```
$ ./asn1_print /tmp/t490/ek2.crt Certificate |
jq '.tbsCertificate.extensions[3]._extnValue[]._values'

This commit adds functions for finding OIDs by symbolic name, meaning by
their symbolic names given in the ASN.1 modules that define them.
TBD:
- Resolve OIDs to names.
- Support a file in /etc for additional OID resolution.
- Add support for resolving OID arc names.
We turn on a few extra warnings and fix the fallout that occurs
when building with --enable-developer. Note that we get different
warnings on different machines and so this will be a work in
progress. So far, we have built on NetBSD/amd64 5.99.64 (which
uses gcc 4.5.3) and Ubuntu 10.04.3 LTS (which uses gcc 4.4.3).
Notably, we fixed
1. a lot of missing structure initialisers,
2. unchecked return values for functions that glibc
marks as __attribute__((warn-unused-result)),
3. made minor modifications to slc and asn1_compile
which can generate code which generates warnings,
and
4. a few stragglers here and there.
We turned off the extended warnings for many programs in appl/ as
they are nearing the end of their useful lifetime, e.g. rsh, rcp,
popper, ftp and telnet.
Interestingly, glibc's strncmp() macro needed to be worked around
whereas the function calls did not.
We have not yet tried this on 32 bit platforms, so there will be
a few more warnings when we do.
Highlighs for the compiler is support for CHOICE and in general better
support for tags. This compiler support most of what is needed for
PK-INIT, LDAP, X.509, PKCS-12 and many other protocols.
