revlogv2: simplify and clarify the processing of each entry
As we add more entries and some of them has non trivial processing it seems
useful to make the processing leaner and clearly separated to simplify futures
patches.

revlogv2: use a unique filename for data
Having a unique data will allow for ambiguity less rewriting of revlog content,
something useful to clarify handling of some operation like censoring or
stripping.

rhg: A missing .hg/dirstate file is not an error
Instead treat it as like an empty file

rhg: Sort `rhg status` output correctly
* The relative order of states is:
modified, added, removed, deleted, unknown, ignored, clean
* Files in the same state should be sorted by name, regardless of whether
or not the were in "unsure" state based on metadata alone.

dirstate-v2: Add `hg debugupgraderepo` command support
This command changes changes the file formats used inside an existing
repository to what they would be in a new repository with the current config.
For example:
hg debugupgraderepo --config format.exp-dirstate-v2=1 --run
hg debugupgraderepo --config format.exp-dirstate-v2=0 --run
If a repository has a dirstate in v1 format, the first command would upgrade it
to dirstate-v2. Conversely, if a repository has a dirstate in v2 format, the
second command would downgrade it to v1. (Both may also run some unrelated
upgrades.)
Since `format.exp-dirstate-v2` is currently disabled by default, not specifying
it in `--config` or any configuration file would result in the second command.

upgrade: Use `improvement` subclasses everywhere, not instances
This changes the source definition of optimizations to match that of formats:
a subclass with a decorator, instead of an instance passed to a function call.
Not having any instance removes the confusion between class attributes and
instance attributes, which were used interchangeably.

exewrapper: avoid directly linking against python3X.dll
Subsequent code calls `LoadLibrary()` to attempt to load the DLL, but because of
this symbol reference, there is an attempt to load the DLL used during the build
prior to `_main()` running. This causes the whole process to fail if the DLL
isn't in the standard search path. That also means it will never load the DLL
for HackableMercurial. (Maybe we should get rid of that for py3, since you can
install python for a user without admin rights?)
This could also be resolved by calling `GetProcAddress()` on the symbol and
dereferencing it, but using the environment variable is consistent with the
*.bat file since fc8a5c9ecee0. (The environment variable persists after the
interpreter is initialized.)
Far more concerning is somehow I've gotten my system into a state where setting
the flag causes any output to the pager to be lost (as if it wasn't set at all)
in MSYS, cmd.exe, WSL, and PowerShell using py3.9.0, but the environment
variable works properly. I'm sure this flag worked on some versions of py3, so
I'm not sure what's going on here. This is might be related to init config
related changes in 3.8[1], since it works with 3.7.8, but fails with 3.8.1.
Somebody who understands encoding issues better than I do should give some
thought to if we need to make some changes to our encoding strategy on Windows
with py3.
With or without the flag/envvar, there is proper output if the command is
directly paged by piping to `more.com` (in any environment) or `less` (in MSYS
and WSL), or if paging is disabled with `--pager=no`. Legacy mode is required
though when Mercurial decides to spin up a pager.
