templater: enable alias predicates to be used in "revset()" function
Before this patch, predicates defined in "[revsetalias]" can't be used
in the query specified to template function "revset()", because:
- "revset()" uses "localrepository.revs()" to get query result, but
- "localrepository.revs()" passes "None" as "ui" to "revset.match()", then
- "revset.match()" can't recognize any alias predicates
To enable alias predicates to be used in "revset()" function, this
patch invokes "revset.match()" directly with "repo.ui".
This patch doesn't make "localrepository.revs()" pass "self.ui" to
"revset.match()", because this may be intentional implementation to
prevent alias predicates from shadowing built-in ones and breaking
functions internally using "localrepository.revs()".
Even if it isn't intentional one, the check for shadowing should be
implemented (maybe on default branch) before fixing it for safety.

Mercurial supports several ways to specify individual revisions. A plain integer is treated as a revision number. Negative integers are treated as sequential offsets from the tip, with -1 denoting the tip, -2 denoting the revision prior to the tip, and so forth. A 40-digit hexadecimal string is treated as a unique revision identifier. A hexadecimal string less than 40 characters long is treated as a unique revision identifier and is referred to as a short-form identifier. A short-form identifier is only valid if it is the prefix of exactly one full-length identifier. Any other string is treated as a bookmark, tag, or branch name. A bookmark is a movable pointer to a revision. A tag is a permanent name associated with a revision. A branch name denotes the tipmost open branch head of that branch - or if they are all closed, the tipmost closed head of the branch. Bookmark, tag, and branch names must not contain the ":" character. The reserved name "tip" always identifies the most recent revision. The reserved name "null" indicates the null revision. This is the revision of an empty repository, and the parent of revision 0. The reserved name "." indicates the working directory parent. If no working directory is checked out, it is equivalent to null. If an uncommitted merge is in progress, "." is the revision of the first parent.
