configitems: declare items in a TOML file

configitems: declare items in a TOML file

Mercurial ships with Rust code that also needs to read from the config.
Having a way of presenting `configitems` to both Python and Rust is needed
to prevent duplication, drift, and have the appropriate devel warnings.

Abstracting away from Python means choosing a config format. No single format
is perfect, and I have yet to come across a developer that doesn't hate all of
them in some way.
Since we have a strict no-dependencies policy for Mercurial, we either need
to use whatever comes with Python, vendor a library, or implement a custom
format ourselves.

Python stdlib means using JSON, which doesn't support comments and isn't great
for humans, or `configparser` which is an obscure, untyped format that nobody
uses and doesn't have a commonplace Rust parser.
Implementing a custom format is error-prone, tedious and subject to the
same issues as picking an existing format.

Vendoring opens us to the vast array of common config formats. The ones
being picked for most modern software are YAML and TOML. YAML is older and
common in the Python community, but TOML is much simpler and less error-prone.
I would much rather be responsible for the <1000 lines of `tomli`, on top of
TOML being the choice of the Rust community, with robust crates for reading it.

The structure of `configitems.toml` is explained inline.

-#      - for stripping operation
-#      - for rollback operation
-# * proper streaming (race free) of the docket file
-# * track garbage data to evemtually allow rewriting -existing- sidedata.
-# * Exchange-wise, we will also need to do something more efficient than
-#   keeping references to the affected revlogs, especially memory-wise when
-#   rewriting sidedata.
-# * introduce a proper solution to reduce the number of filelog related files.
-# * use caching for reading sidedata (similar to what we do for data).
-# * no longer set offset=0 if sidedata_size=0 (simplify cutoff computation).
-# * Improvement to consider
-#   - avoid compression header in chunk using the default compression?
-#   - forbid "inline" compression mode entirely?
-#   - split the data offset and flag field (the 2 bytes save are mostly trouble)
-#   - keep track of uncompressed -chunk- size (to preallocate memory better)
-#   - keep track of chain base or size (probably not that useful anymore)
