/*
* Implementation of scf_walk_fmri()
*
* This is a little tricky due to the many-to-many relationship between patterns
* and matches. We need to be able to satisfy the following requirements:
*
* 1) Detect patterns which match more than one FMRI, and be able to
* report which FMRIs have been matched.
* 2) Detect patterns which have not matched any FMRIs
* 3) Visit each matching FMRI exactly once across all patterns
* 4) Ignore FMRIs which have only been matched due to multiply-matching
* patterns.
*
* We maintain an array of scf_pattern_t structures, one for each argument, and
* maintain a linked list of scf_match_t structures for each one. We first
* qualify each pattern's type:
*
* PATTERN_INVALID The argument is invalid (too long).
*
* PATTERN_EXACT The pattern is a complete FMRI. The list of
* matches contains only a single entry.
*
* PATTERN_GLOB The pattern will be matched against all
* FMRIs via fnmatch() in the second phase.
* Matches will be added to the pattern's list
* as they are found.
*
* PATTERN_PARTIAL Everything else. We will assume that this is
* an abbreviated FMRI, and match according to
* our abbreviated FMRI rules. Matches will be
* added to the pattern's list as they are found.
*
* The first pass searches for arguments that are complete FMRIs. These are
* classified as EXACT patterns and do not necessitate searching the entire
* tree.
*
* Once this is done, if we have any GLOB or PARTIAL patterns (or if no
* arguments were given), we iterate over all services and instances in the
* repository, looking for matches.
*
* When a match is found, we add the match to the pattern's list. We also enter
* the match into a hash table, resulting in something like this:
*
* scf_pattern_t scf_match_t
* +---------------+ +-------+ +-------+
* | pattern 'foo' |----->| match |---->| match |
* +---------------+ +-------+ +-------+
* | |
* scf_match_key_t | |
* +--------------+ | |
* | FMRI bar/foo |<----+ |
* +--------------+ |
* | FMRI baz/foo |<------------------+
* +--------------+
*
* Once we have all of this set up, we do one pass to report patterns matching
* multiple FMRIs (if SCF_WALK_MULTIPLE is not set) and patterns for which no
* match was found.
*
* Finally, we walk through all valid patterns, and for each match, if we
* haven't already seen the match (as recorded in the hash table), then we
* execute the callback.
