This adds a fallback directory in case SYSTEM_LOCKFILE_DIR is
unavailable. Since this is a band-aid meant to help older systems
auto-update, the fallback path is hardcoded to "/tmp" as to avoid
polluting the overall lockfile API.

The Filesystem Hierarchy Standard version 3.0* specifies that /run
should be used for runtime variables such as locks.
The rationale for switching to use /run instead of /var/run was
because /var might not be available at early boot. Since /run is
implemented as a tmpfs and doesn't require /var to be mounted first
it can be made available earlier.

Some systems, such as Android, do not support SysV semaphore locks.
This implements an alternative file lock mechanism using flock().
flock() was chosen because it's pretty straight forward. It's known to
be broken when using NFS, but I doubt we'll ever store our lock on an
NFS volume.

This adds a couple of helper functions for working within Android:
- in_android(): Crude test that uses getenv() to see if an Android-
specific environment variable is defined.
- android_tmpdir_path(): Android doesn't have the usual locations for
temporary file storage such as /tmp or even /var/run/locks. And to
make matters worse, there isn't even a standard location for
temporary files so it must be determined at run time.
This will be used in a follow-up patch.

This make minor syntactic changes and renames some camel-cased symbols
to keep checkpatch from complaining. The goal is to reduce the
temptation to use 'repo upload --no-verify'.
This is a big furball of find/replace, but no functional changes.

Instead of hardcoding the common files for host utils in the generic
rules, let's declare them in the build.mk file using the same system as
the Linux kernel build.
if a binary "foo" declared in "host-util-bin" or "build-util-bin" has a
matching "foo-objs" variable, it will be build from all objects declared
in "foo-objs" else it uses directly "foo.o" (single source file).
This is preparatory to add new "build" tools sharing common sources.
note: the dependencies on the utils are a bit less fine-grained as a
result of this change, but given the low number of tools, that should be
acceptable.
