Bi-Ruei, Chiu 50934ba3d4 Fix 'Information Object Set XXX contains no objects' when parsing S1AP's ASN.1
The aforementioned error message displayed during processing the following ASN.1 excerpt.

S1AP-ELEMENTARY-PROCEDURES S1AP-ELEMENTARY-PROCEDURE ::= {
    S1AP-ELEMENTARY-PROCEDURES-CLASS-1 |
    S1AP-ELEMENTARY-PROCEDURES-CLASS-2,
    ...
}

S1AP-ELEMENTARY-PROCEDURES-CLASS-1 S1AP-ELEMENTARY-PROCEDURE ::= {
    handoverPreparation                |
...
    writeReplaceWarning,
    ...,
    uERadioCapabilityMatch             |
....
    uEContextResume
}

S1AP-ELEMENTARY-PROCEDURES-CLASS-2 S1AP-ELEMENTARY-PROCEDURE ::= {
    handoverNotification               |
...
    privateMessage,
    ...,
    downlinkUEAssociatedLPPaTransport  |
...
    mMECPRelocationIndication
}

Because S1AP-ELEMENTARY-PROCEDURES-CLASS-1 and S1AP-ELEMENTARY-PROCEDURES-CLASS-2
are resolved 'after' S1AP-ELEMENTARY-PROCEDURES, so the ioc tables of them are not
available during resolving S1AP-ELEMENTARY-PROCEDURES. So we can not drop the
latter's containedSubtype field at first pass of asn1f_resolve_constraints of fix
process.

We also add second pass of asn1f_resolve_constraints to have a chance to combine
ioc tables of S1AP-ELEMENTARY-PROCEDURES-CLASS-1 and
S1AP-ELEMENTARY-PROCEDURES-CLASS-2.

Bi-Ruei, Chiu 80fd3065f4 Merge PR99 and its fixes to support parsing Information Object and Information Object Set
This is a collection of works :

1. Based on @zhanglei002's pull request 99.

2. A fix by @AuthenticEshkinKot and merged by @mouse07410 at
   commit 2c8d366bbe1fc4e4c041e9b0eb9779f8a42d754b of https://github.com/mouse07410/asn1c
   to support parsing of Information Object and Information Object Set

3. A fix by @Uri Blumenthal in asn1fix_derefv.c at :
   commit ec0ade4f87c807e763e3f35fc5466adb6dda3473 of https://github.com/mouse07410/asn1c
   to solve crash on asn1p_value_free().

4. My pull request 18 to @mouse07410's https://github.com/mouse07410/asn1c to solve
   problems found during parsing ASN.1 modules of S1AP, RANAP and J2735-201603.

5. My pull request 22 to @mouse07410's https://github.com/mouse07410/asn1c to solve issue 147
