templater: use template context to render old-style list template
Prepares for dropping the 'templ' resource.
This means old-style list templates are processed by the same engine class
as the one for the list node. I think that's fine since templates for the
same list should be tightly coupled, and I believe the extension point for
the engine classes isn't actually used.
Now templatekw._showlist() is a compatibility wrapper for _showcompatlist(),
and will be deprecated soon. The function is still marked as private since
I plan to change the interface to get rid of closures capturing context and
mapping.

Mercurial supports a functional language for selecting a set of files. Like other file patterns, this pattern type is indicated by a prefix, 'set:'. The language supports a number of predicates which are joined by infix operators. Parenthesis can be used for grouping. Identifiers such as filenames or patterns must be quoted with single or double quotes if they contain characters outside of ``[.*{}[]?/\_a-zA-Z0-9\x80-\xff]`` or if they match one of the predefined predicates. This generally applies to file patterns other than globs and arguments for predicates. Pattern prefixes such as ``path:`` may be specified without quoting. Special characters can be used in quoted identifiers by escaping them, e.g., ``\n`` is interpreted as a newline. To prevent them from being interpreted, strings can be prefixed with ``r``, e.g. ``r'...'``. See also :hg:`help patterns`. Operators ========= There is a single prefix operator: ``not x`` Files not in x. Short form is ``! x``. These are the supported infix operators: ``x and y`` The intersection of files in x and y. Short form is ``x & y``. ``x or y`` The union of files in x and y. There are two alternative short forms: ``x | y`` and ``x + y``. ``x - y`` Files in x but not in y. Predicates ========== The following predicates are supported: .. predicatesmarker Examples ======== Some sample queries: - Show status of files that appear to be binary in the working directory:: hg status -A "set:binary()" - Forget files that are in .hgignore but are already tracked:: hg forget "set:hgignore() and not ignored()" - Find text files that contain a string:: hg files "set:grep(magic) and not binary()" - Find C files in a non-standard encoding:: hg files "set:**.c and not encoding('UTF-8')" - Revert copies of large binary files:: hg revert "set:copied() and binary() and size('>1M')" - Revert files that were added to the working directory:: hg revert "set:revs('wdir()', added())" - Remove files listed in foo.lst that contain the letter a or b:: hg remove "set: listfile:foo.lst and (**a* or **b*)"
