This can be used to run the test tool without installing it.
It sets the environment variables and command line arguments
up correctly to run the tool from the build directory.

These are missing on Mac OS X.  I think you would need to install
a gettext package to get these.

guestfs_mount adds -o sync implicitly.  This causes a very large
performance problem for write-intensive programs (eg. virt-v2v).

Document this as a "gotcha".

Change the tests, guestfish, Sys::Guestfs::Lib, guestmount to use
mount-options instead.

(Note that this gotcha does not affect mount-ro).

The source of the performance problem was first identified by
Matthew Booth.

This commit adds the calls to setlocale &c to all of the current
C programs.

It also adds l10n support to hivexget and hivexml which lacked them
previously.

To test this, try:

LANG=pa_IN.UTF-8 guestfish --cmd-help

(You can only do this test after installing the package, or at
least the 'pa.mo' mo-file in the correct place).

Convert all uses automatically, via these two commands:
git grep -l '\<exit *(1)' \
  | grep -vEf .x-sc_prohibit_magic_number_exit \
  | xargs --no-run-if-empty \
    perl -pi -e 's/\b(exit ?)\(1\)/$1(EXIT_FAILURE)/'
git grep -l '\<exit *(0)' \
  | grep -vEf .x-sc_prohibit_magic_number_exit \
  | xargs --no-run-if-empty \
  perl -pi -e 's/\b(exit ?)\(0\)/$1(EXIT_SUCCESS)/'
* .x-sc_prohibit_magic_number_exit: New file.

Edit (RWMJ): Don't change Java code.

This change adds an explicit dependency on generator.ml for every file it
generates, except java files. Java is left for another time because it's
considerably trickier.

It also adds a build rule for src/libguestfs.la so it can be rebuilt as required
from other directories.

It does this by creating a top level make file, subdir-rules.mk, which can be
included from sub-directories. sub-directories need to define 'generator_built'
to include local files which are built by generator.ml, and they will be updated
automatically.

This fixes parallel make, and will automatically re-create generated files when
make is run from any directory.

It also fixes the problem which efad4f53 was targetting. Specifically,
src/guestfs_protocol.(c|h) had an erroneous dependency on stamp-generator, and
therefore generator.ml, despite not being directly created by it. This caused
them to be recreated every time generator.ml ran rather than only when
src/guestfs_protocol.x was updated, which cascaded into a daemon and therefore
appliance update.

This patch also changes the contents of the distribution tarball by including
files created by rpcgen.

Move these to private header file(s) and other places as required
since these aren't part of the public API.
