revlog: rename 'self.checkinlinesize' into '_enforceinlinesize'
The name change has two motivations:
1) The function has no external caller, so we move it to protected space.
2) the function does more than checking it also split the data if we have more
data than 'inline' supports.
#testcases lfsremote-on lfsremote-off
#require serve
This test splits `hg serve` with and without using the extension into separate
tests cases. The tests are broken down as follows, where "LFS"/"No-LFS"
indicates whether or not there are commits that use an LFS file, and "D"/"E"
indicates whether or not the extension is loaded. The "X" cases are not tested
individually, because the lfs requirement causes the process to bail early if
the extension is disabled.

$ hg init server

Skip the experimental.changegroup3=True config. Failure to agree on this comes
first, and causes a "ValueError: no common changegroup version" or "abort:
HTTP Error 500: Internal Server Error", if the extension is only loaded on one
side. If that *is* enabled, the subsequent failure is "abort: missing processor
for flag '0x2000'!" if the extension is only loaded on one side (possibly also
masked by the Internal Server Error message).

Since no lfs content has been added yet, the push is allowed, even when the
extension is not enabled remotely.

Case #3: client with lfs content and the extension enabled; server with
non-lfs content, and the extension state controlled by #testcases. The server
should have an 'lfs' requirement after it picks up its first commit with a blob.

The difference here is the push failed above when the extension isn't
enabled on the server.
$ hg identify http://localhost:$HGPORT

Don't bother testing the lfsremote-off cases- the server won't be able
to launch if there's lfs content and the extension is disabled.
