filemerge: add support for partial conflict resolution by external tool
A common class of merge conflicts is in imports/#includes/etc. It's
relatively easy to write a tool that can resolve these conflicts,
perhaps by naively just unioning the statements and leaving any
cleanup to other tools to do later [1]. Such specialized tools cannot
generally resolve all conflicts in a file, of course. Let's therefore
call them "partial merge tools". Note that the internal simplemerge
algorithm is such a partial merge tool - one that only resolves
trivial "conflicts" where one side is unchanged or both sides change
in the same way.
One can also imagine having smarter language-aware partial tools that
merge the AST. It may be useful for such tools to interactively let
the user resolve any conflicts it can't resolve itself. However,
having the option of implementing it as a partial merge tool means
that the developer doesn't *need* to create a UI for it. Instead, the
user can resolve any remaining conflicts with their regular merge tool
(e.g. `:merge3` or `meld).
We don't currently have a way to let the user define such partial
merge tools. That's what this patch addresses. It lets the user
configure partial merge tools to run. Each tool can be configured to
run only on files matching certain patterns (e.g. "*.py"). The tool
takes three inputs (local, base, other) and resolves conflicts by
updating these in place. For example, let's say the inputs are these:
base:
```
import sys
def main():
print('Hello')
```
local:
```
import os
import sys
def main():
print('Hi')
```
other:
```
import re
import sys
def main():
print('Howdy')
```
A partial merge tool could now resolve the conflicting imports by
replacing the import statements in *all* files by the following
snippet, while leaving the remainder of the files unchanged.
```
import os
import re
import sys
```
As a result, simplemerge and any regular merge tool that runs after
the partial merge tool(s) will consider the imports to be
non-conflicting and will only present the conflict in `main()` to the
user.

Test order of revisions in compound expression
----------------------------------------------
The general rule is that only the outermost (= leftmost) predicate can
enforce its ordering requirement. The other predicates should take the
ordering defined by it.
'A & B' should follow the order of 'A':
$ log '2:0 & 0::2'
2
1
0
'head()' combines sets in right order:
$ log '2:0 & head()'
2
1
0
'x:y' takes ordering parameter into account:
$ try -p optimized '3:0 & 0:3 & not 2:1'
* optimized:
(difference
(and
(range
(symbol '3')
(symbol '0'))
(range
(symbol '0')
(symbol '3')))
(range
(symbol '2')
(symbol '1')))
* set:
<filteredset
<filteredset
<spanset- 0:4>,
<spanset+ 0:4>>,
<not
<spanset+ 1:3>>>
3
0
'a + b', which is optimized to '_list(a b)', should take the ordering of
the left expression:
$ try --optimize '2:0 & (0 + 1 + 2)'
(and
(range
(symbol '2')
(symbol '0'))
(group
(or

(symbol '0')

* set:

'A + B' should take the ordering of the left expression:

'_list' should not go through the slow follow-order path if order doesn't
matter:
