merge: use separate lists for each action type
This replaces the grand unified action list that had multiple action types as
tuples in one big list. That list was iterated multiple times just to find
actions of a specific type. This data model also made some code more
convoluted than necessary.
Instead we now store actions as a tuple of lists. Using multiple lists gives a
bit of cut'n'pasted code but also enables other optimizations.
This patch uses 'if True:' to preserve indentations and help reviewing. It also
limits the number of conflicts with other pending patches. It can trivially be
cleaned up later.

use 'echo' to diff repository (or selected files)
Show differences between revisions for the specified files, using the
'echo' program.
When two revision arguments are given, then changes are shown between
those revisions. If only one revision is specified then that revision is
compared to the working directory, and, when no revisions are specified,
the working directory files are compared to its parent.
options:
-o --option OPT [+] pass option to comparison program
-r --rev REV [+] revision
-c --change REV change made by revision
-I --include PATTERN [+] include names matching the given patterns
-X --exclude PATTERN [+] exclude names matching the given patterns
[+] marked option can be specified multiple times
use "hg -v help falabala" to show the global options

$ hg merge 1
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
(branch merge, don't forget to commit)
