upgrade: only process revlogs that needs it by default

We have more and more requirement that does not affect revlog or that only
affect some of them. It is silly to force a full processing of all revlog to
juste move the requirement around, or to simply rewrite the dirstate.

So now, only the revlog that needs to be touched will be touched. Unless the
--changelog & al flags are used.

#require sqlite no-chg

The sqlitestore backend leaves transactions around when used with chg.
Since this backend is primarily intended as proof-of-concept for
alternative storage backends, disable it for chg test runs to avoid
the instability.

New repo should not use SQLite by default

  $ hg init empty-no-sqlite
  $ cat empty-no-sqlite/.hg/requires
  dotencode
  dirstate-v2 (dirstate-v2 !)
  fncache
  generaldelta
  persistent-nodemap (rust !)
  revlog-compression-zstd (zstd !)
  revlogv1
  sparserevlog
  store

storage.new-repo-backend=sqlite is recognized

  $ hg --config storage.new-repo-backend=sqlite init empty-sqlite
  $ cat empty-sqlite/.hg/requires
  dotencode
  dirstate-v2 (dirstate-v2 !)
  exp-sqlite-001
  exp-sqlite-comp-001=zstd (zstd !)
  exp-sqlite-comp-001=$BUNDLE2_COMPRESSIONS$ (no-zstd !)
  fncache
  generaldelta
  persistent-nodemap (rust !)
  revlog-compression-zstd (zstd !)
  revlogv1
  sparserevlog
  store

  $ cat >> $HGRCPATH << EOF

Can force compression to zlib

  $ hg --config storage.sqlite.compression=zlib init empty-zlib
  $ cat empty-zlib/.hg/requires
  dotencode
  dirstate-v2 (dirstate-v2 !)
  exp-sqlite-001
  exp-sqlite-comp-001=$BUNDLE2_COMPRESSIONS$
  fncache
  generaldelta
  persistent-nodemap (rust !)
  revlog-compression-zstd (zstd !)
  revlogv1
  sparserevlog
  store

Can force compression to none

  $ hg --config storage.sqlite.compression=none init empty-none
  $ cat empty-none/.hg/requires
  dotencode
  dirstate-v2 (dirstate-v2 !)
  exp-sqlite-001
  exp-sqlite-comp-001=none
  fncache
  generaldelta
  persistent-nodemap (rust !)
  revlog-compression-zstd (zstd !)
  revlogv1
  sparserevlog
  store

Can make a local commit

  $ hg init local-commit
  $ cd local-commit
  $ echo 0 > foo
  $ hg commit -A -m initial
  adding foo

That results in a row being inserted into various tables

  $ sqlite3 .hg/store/db.sqlite -init /dev/null << EOF
  > SELECT * FROM filepath;
  > EOF
  1|foo

  $ sqlite3 .hg/store/db.sqlite -init /dev/null << EOF
  > SELECT * FROM fileindex;
  > EOF
  1|1|0|-1|-1|0|0|1||6/\xef(L\xe2\xca\x02\xae\xcc\x8d\xe6\xd5\xe8\xa1\xc3\xaf\x05V\xfe (esc)

  $ sqlite3 .hg/store/db.sqlite -init /dev/null << EOF
  > SELECT * FROM delta;
  > EOF
  1|1|	\xd2\xaf\x8d\xd2"\x01\xdd\x8dH\xe5\xdc\xfc\xae\xd2\x81\xff\x94"\xc7|0 (esc)
  

Tracking multiple files works

  $ echo 1 > bar
  $ hg commit -A -m 'add bar'
  adding bar

  $ sqlite3 .hg/store/db.sqlite -init /dev/null << EOF
  > SELECT * FROM filedata ORDER BY id ASC;
  > EOF
  1|1|foo|0|6/\xef(L\xe2\xca\x02\xae\xcc\x8d\xe6\xd5\xe8\xa1\xc3\xaf\x05V\xfe|-1|-1|0|0|1| (esc)
  2|2|bar|0|\xb8\xe0/d3s\x80!\xa0e\xf9Au\xc7\xcd#\xdb_\x05\xbe|-1|-1|1|0|2| (esc)

Multiple revisions of a file works

  $ echo a >> foo
  $ hg commit -m 'modify foo'

  $ sqlite3 .hg/store/db.sqlite -init /dev/null << EOF
  > SELECT * FROM filedata ORDER BY id ASC;
  > EOF
  1|1|foo|0|6/\xef(L\xe2\xca\x02\xae\xcc\x8d\xe6\xd5\xe8\xa1\xc3\xaf\x05V\xfe|-1|-1|0|0|1| (esc)
  2|2|bar|0|\xb8\xe0/d3s\x80!\xa0e\xf9Au\xc7\xcd#\xdb_\x05\xbe|-1|-1|1|0|2| (esc)
  3|1|foo|1|\xdd\xb3V\xcd\xde1p@\xf7\x8e\x90\xb8*\x8b,\xe9\x0e\xd6j+|0|-1|2|0|3|1 (esc)
