memctx: calculate exact status being committed from specified files
Before this patch, "memctx._status" is initialized by "(files, [], [],
[], [], [], [])" and this causes "memctx.modified" to include not
only modified files but also added and removed ones incorrectly.
This patch adds "_status" method to calculate exact status being
committed according to "files" specified at construction time.
Exact "_status" is useful to share/reuse logic of committablectx.
This patch is also preparation for issues fixed by subsequent patches.
Some details of changes for tests in this patch:
- some filename lines are omitted in "test-convert-svn-encoding.t",
because they are correctly listed up as "removed" files
those lines are written out in "localrepository.commitctx" for
"modified" and "added" files by "ui.note".
- "| fixbundle" filterring in "test-histedit-fold.t" is omitted to
check lines including "added" correctly
"fixbundle" discards all lines including "added".
