clonebundles: filter on bundle specification

Not all clients are capable of reading every bundle. Currently, content
negotiation to ensure a server sends a client a compatible bundle
format is performed at request time. The response bundle is dynamically
generated at request time, so this works fine.

Clone bundles are statically generated *before* the request. This means
that a modern server could produce bundles that a legacy client isn't
capable of reading. Without some kind of "type hint" in the clone
bundles manifest, a client may attempt to download an incompatible
bundle. Furthermore, a client may not realize a bundle is incompatible
until it has processed part of the bundle (imagine consuming a 1 GB
changegroup bundle2 part only to discover the bundle2 part afterwards is
incompatibl). This would waste time and resources. And it isn't very
user friendly.

Clone bundle manifests thus need to advertise the *exact* format of the
hosted bundles so clients may filter out entries that they don't know
how to read. This patch introduces that mechanism.

We introduce the BUNDLESPEC attribute to declare the "bundle
specification" of the entry. Bundle specifications are parsed using
exchange.parsebundlespecification, which uses the same strings as the
"--type" argument to `hg bundle`. The supported bundle specifications
are well defined and backwards compatible.

When a client encounters a BUNDLESPEC that is invalid or unsupported, it
silently ignores the entry.

Preparing the subrepository 'sub2'

  $ hg init sub2
  $ echo sub2 > sub2/sub2
  $ hg add -R sub2
  adding sub2/sub2 (glob)
  $ hg commit -R sub2 -m "sub2 import"

Preparing the 'sub1' repo which depends on the subrepo 'sub2'

  $ hg init sub1
  $ echo sub1 > sub1/sub1
  $ echo "sub2 = ../sub2" > sub1/.hgsub
  $ hg clone sub2 sub1/sub2
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg add -R sub1
  adding sub1/.hgsub (glob)
  adding sub1/sub1 (glob)
  $ hg commit -R sub1 -m "sub1 import"

Preparing the 'main' repo which depends on the subrepo 'sub1'

  $ hg init main
  $ echo main > main/main
  $ echo "sub1 = ../sub1" > main/.hgsub
  $ hg clone sub1 main/sub1
  updating to branch default
  cloning subrepo sub2 from $TESTTMP/sub2
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg add -R main
  adding main/.hgsub (glob)
  adding main/main (glob)
  $ hg commit -R main -m "main import"

Cleaning both repositories, just as a clone -U

  $ hg up -C -R sub2 null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg up -C -R sub1 null
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ hg up -C -R main null
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ rm -rf main/sub1
  $ rm -rf sub1/sub2

Clone main

  $ hg --config extensions.largefiles= clone main cloned
  updating to branch default
  cloning subrepo sub1 from $TESTTMP/sub1
  cloning subrepo sub1/sub2 from $TESTTMP/sub2 (glob)
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved

Largefiles is NOT enabled in the clone if the source repo doesn't require it
  $ cat cloned/.hg/hgrc
  # example repository config (see "hg help config" for more info)
  [paths]
  default = $TESTTMP/main (glob)
  
  # path aliases to other clones of this repo in URLs or filesystem paths
  # (see "hg help config.paths" for more info)
  #
  # default-push = ssh://[e-mail]/hg/jdoes-fork
  # my-fork      = ssh://[e-mail]/hg/jdoes-fork
  # my-clone     = /home/jdoe/jdoes-clone
