Jun Wu 66cef07cf9 indexedlog: add a fsync option to Log and Index
Summary:
Add a way to explicitly `fsync` data to reduce changes of data corruption in
case of hard reboots.

If `fsync` is set on a `Log`, it sets `fsync` recursively on its indexes and
checksum tables. If frequent `fsync` is an issue, it might be possible to only
`fsync` the source of truth (log and meta) and have other logic to rebuild
indexes on demand.

`fsync` on btrfs seems to be relatively cheap (comparing to ext4), so maybe
this is fine for btrfs users.

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install::

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing::

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.
