fb2c81f3e8 asn1: Add printing of ASN.1 values 
JSON-like printing of ASN.1 parsed values.

Status:

 - Not X.697 (JER) compliant, not even close.

 - String escaping isn't JSON-compliant.

 - It's not printing the names of CHOICE types.

 - It's not printing the names of open type choices (i.e., IOS object
   names)

And yet it's quite useful already.  It prints all the weird things in EK
certs for example.

Here's what it outputs for the EK cert we use in check-gen.c:

db7763ca7b asn1: X.681/682/683 magic handling of open types 
Status:

 - And it works!

 - We have an extensive test based on decoding a rich EK certficate.

   This test exercises all of:

    - decoding
    - encoding with and without decoded open types
    - copying of decoded values with decoded open types
    - freeing of decoded values with decoded open types

   Valgrind finds no memory errors.

 - Added a manual page for the compiler.

 - rfc2459.asn1 now has all three primary PKIX types that we care about
   defined as in RFC5912, with IOS constraints and parameterization:

    - `Extension`       (embeds open type in an `OCTET STRING`)
    - `OtherName`       (embeds open type in an        `ANY`-like type)
    - `SingleAttribute` (embeds open type in an        `ANY`-like type)
    - `AttributeSet`    (embeds open type in a  `SET OF ANY`-like type)

   All of these use OIDs as the open type type ID field, but integer
   open type type ID fields are also supported (and needed, for
   Kerberos).

   That will cover every typed hole pattern in all our ASN.1 modules.

   With this we'll be able to automatically and recursively decode
   through all subject DN attributes even when the subject DN is a
   directoryName SAN, and subjectDirectoryAttributes, and all
   extensions, and all SANs, and all authorization-data elements, and
   PA-data, and...

   We're not really using `SingleAttribute` and `AttributeSet` yet
   because various changes are needed in `lib/hx509` for that.

 - `asn1_compile` builds and recognizes the subset of X.681/682/683 that
   we need for, and now use in, rfc2459.asn1.  It builds the necessary
   AST, generates the correct C types, and generates templating for
   object sets and open types!

 - See READMEs for details.

 - Codegen backend not tested; I won't make it implement automatic open
   type handling, but it should at least not crash by substituting
   `heim_any` for open types not embedded in `OCTET STRING`.

 - We're _really_ starting to have problems with the ITU-T ASN.1
   grammar and our version of it...

   Type names have to start with upper-case, value names with
   lower-case, but it's not enough to disambiguate.

   The fact the we've allowed value and type names to violate their
   respective start-with case rules is causing us trouble now that we're
   adding grammar from X.681/682/683, and we're going to have to undo
   that.

   In preparation for that I'm capitalizing the `heim_any` and
   `heim_any_set` types, and doing some additional cleanup, which
   requires changes to other parts of Heimdal (all in this same commit
   for now).

   Problems we have because of this:

    - We cannot IMPORT values into modules because we have no idea if a
      symbol being imported refers to a value or a type because the only
      clue we would have is the symbol's name, so we assume IMPORTed
      symbols are for types.

      This means we can't import OIDs, for example, which is super
      annoying.

      One thing we might be able to do here is mark imported symbols as
      being of an undetermined-but-not-undefined type, then coerce the
      symbol's type the first time it's used in a context where its type
      is inferred as type, value, object, object set, or class.  (Though
      since we don't generate C symbols for objects or classes, we won't
      be able to import them, especially since we need to know them at
      compile time and cannot defer their handling to link- or
      run-time.)

    - The `NULL` type name, and the `NULL` value name now cause two
      reduce/reduce conflicts via the `FieldSetting` production.

    - Various shift/reduce conflicts involving `NULL` values in
      non-top-level contexts (in constraints, for example).

 - Currently I have a bug where to disambiguate the grammar I have a
   CLASS_IDENTIFIER token that is all caps, while TYPE_IDENTIFIER must
   start with a capital but not be all caps, but this breaks Kerberos
   since all its types are all capitalized -- oof!

   To fix this I made it so class names have to be all caps and
   start with an underscore (ick).

TBD:

 - Check all the XXX comments and address them
 - Apply this treatment to Kerberos!  Automatic handling of authz-data
   sounds useful :)
 - Apply this treatment to PKCS#10 (CSRs) and other ASN.1 modules too.
 - Replace various bits of code in `lib/hx509/` with uses of this
   feature.
 - Add JER.
 - Enhance `hxtool` and `asn1_print`.

Getting there!

19d378f44d Add 64-bit integer support to ASN.1 compiler 
ASN.1 INTEGERs will now compile to C int64_t or uint64_t, depending
    on whether the constraint ranges include numbers that cannot be
    represented in 32-bit ints and whether they include negative
    numbers.

    Template backend support included.  check-template is now built with
    --template, so we know we're testing it.

    Tests included.
