localrepo: make invalidate avoid invalidating store inside transaction (API)
Before this patch, invalidate() discards in-memory fncache changes,
even inside transaction scope.
Such changes should be written out at closing transaction. Otherwise,
fncache might overlook newly added files. A file overlooked by
fncache isn't accessible via store vfs, even if it actually exists in
store.
On the other hand, a non-existing file in fncache is less harmful,
because fncachestore always examines whether a file actually exists or
not before access. Therefore, discarding in-memory changes can be
safely omitted.
It is typical case that repo.invalidate() in streamclone is executed
inside nested transaction.
This patch makes invalidate() avoid invalidating store inside
transaction.
This patch focuses on describing only how invalidate() changes own
behavior according to activity of transaction. Describing other detail
of invalidate() in docstr will be done in another series, which
refactors invalidate*() functions.

streamclone: force @filecache properties to be reloaded from file
Before this patch, consumev1() invokes repo.invalidate() after closing
transaction, to force @filecache properties to be reloaded from files
at next access, because streamclone writes data into files directly.
But this doesn't work as expected in the case below:
1. at closing transaction, repo._refreshfilecachestats() refreshes
file stat of each @filecache properties with streamclone-ed files
This means that in-memory properties are treated as valid.
2. but streamclone doesn't changes in-memory properties
This means that in-memory properties are actually invalid.
3. repo.invalidate() just forces to examine file stat of @filecache
properties at the first access after it
Such examination should concludes that reloading from file isn't
needed, because file stat was already refreshed at (1).
Therefore, invalid in-memory cached properties (2) are
unintentionally treated as valid (1).
This patch invokes repo.invalidate() with clearfilecache=True, to
force @filecache properties to be reloaded from file at next access.
BTW, it is accidental that repo.invalidate() without
clearfilecache=True in streamclone case seems to work as expected
before this patch.
If transaction is started via "filtered repo" object,
repo._refreshfilecachestats() tries to refresh file stat of each
@filecache properties on "filtered repo" object, even though all of
them are stored into "unfiltered repo" object.
In this case, repo._refreshfilecachestats() does nothing
unintentionally, but this unexpected behavior causes reloading
@filecache properties after repo.invalidate().
This is reason why this patch should be applied before making
_refreshfilecachestats() correctly refresh file stat of @filecache
properties.

debugrevspec: add option to print parsed tree at given stages
"-p <stage>" is useful for investigating parsing stages. With -p option, a
transformed tree is printed no matter if it is changed or not, which allows
us to know valid stage names by "-p all".

manifest: change manifestctx to not inherit from manifestdict
If manifestctx inherits from manifestdict, it requires some weird logic to
lazily load the dict if a piece of information is asked for. This ended up being
complicated and unintuitive to use.
Let's move the dict creation to .read(). This will make even more sense once we
start adding readdelta() and other similar methods to manifestctx.
