util: check for compression engine availability before returning

If a requested compression engine is registered but not available,
requesting it will now abort.

To be honest, I'm not sure if this is the appropriate mechanism
for handling optional compression engines. I won't know until
all uses of compression (bundles, wire protocol, revlogs, etc)
are using the new API and zstd (our planned optional engine)
is implemented. So this API could change.

# An example hgweb CGI script, edit as necessary
# See also https://mercurial-scm.org/wiki/PublishingRepositories

# Path to repo or hgweb config to serve (see 'hg help hgweb')
config = "/path/to/repo/or/config"

# Uncomment and adjust if Mercurial is not installed system-wide
# (consult "installed modules" path from 'hg debuginstall'):
#import sys; sys.path.insert(0, "/path/to/python/lib")

# Uncomment to send python tracebacks to the browser if an error occurs:
#import cgitb; cgitb.enable()
