Disclose permission intended to be used for "disclose on error"
(as in our present "none"), none being "don't disclose on error".

Manage permission is intended to be used to allow DSA IT management
(e.g., changing entryCSNs, structuralObjectClass, etc.).

support for multi-values attribute in Component Matching

- only for equality matching
- only components of ASN.1 types used in an X.509 certificate can be indexed
(composite types except for RDN and DN are not supported yet)
- how to use
index [attribute name].[component reference] eq
Ex)
index userCertificate eq
index userCertificate.toBeSigned.issuer.rdnSequence eq
index userCertificate.toBeSigned.serialNumber eq
index userCertificate.toBeSigned.version eq

2) attribute aliasing support
- x509CertificateIssuer
- x509CertificateSerial
- x509CertificateIssuerAndIssuer
3) AuthorityKeyIdentifier support(one of certificate extension)
4) Misc. improvement
- integrate OID and its decoder mapping table
- normalize and validate the values of both component asserions and
  extracted components
5) Misc. bug fix

2) nibble type memory support when decoding
3) description type object identifier support
4) OPTIONAL, DEFAULT support in certificate decoder/extractor/matching
5) Misc bug fix

just deleting and adding modified entries.

define OPERATION_BUFFER_SIZE for dummy Operations

remove syncrepl stuff from Operation struct

buddy allocator for sl_malloc. Configurable at thread heap creation time. Need optimization for higher perf.

move ACIs under a dynamic infrastructure that allows run-time loadable custom access control logic (needs work)

add exop_is_write() macro for detecting exops that modify a target entry

partially revert previous commit (the "creator" special DN pattern is redundant as "dnattr" is more expressive
