fileset: use set instead of list to mark predicates for efficiency (API)
This reduces cost of examining whether given predicate calls
'matchctx.status()' or 'matchctx.existing()' in 'getfileset()' at
runtime.
This kind of examination is used also in subsequent patch, which
detects unintentional 'matchctx.existing()' invocation per each
predicate evaluation.

When Mercurial accepts more than one revision, they may be specified individually, or provided as a topologically continuous range, separated by the ":" character. The syntax of range notation is [BEGIN]:[END], where BEGIN and END are revision identifiers. Both BEGIN and END are optional. If BEGIN is not specified, it defaults to revision number 0. If END is not specified, it defaults to the tip. The range ":" thus means "all revisions". If BEGIN is greater than END, revisions are treated in reverse order. A range acts as a closed interval. This means that a range of 3:5 gives 3, 4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.
