Major stuff:
- Created a FileCache for managing user cache files in Spack. Currently just
handles virtuals.
- Moved virtual cache from the repository to the home directory so that users do
not need write access to Spack repositories to use them.
- Refactored `Transaction` class in `database.py` -- moved it to
`LockTransaction` in `lock.py` and made it reusable by other classes.
Other additions:
- Added tests for file cache and transactions.
- Added a few more tests for database
- Fixed bug in DB where writes could happen even if exceptions were raised
during a transaction.
- `spack uninstall` now attempts to repair the database when it discovers that a
prefix doesn't exist but a DB record does.
This does two things:
1. By default `spack find` no longer shows variants. You have to
supply `-v` to get that
2. This improves the `colify` implementation so that it no longer pads
the rightmost column. This avoids the issue where if one spec was
too long in the output, *all* specs would have space padding added
to that width, and it would look like the output of `spack find`
was double spaced. This no longer happens -- the one bad line
wraps around and the other lines are now single-spaced when you use
`-v` with boost.
- Allows skipping the expand step for downloads.
- Fixed stage so that it knows expansion didn't fail when there is a
no-expand URLFetchStrategy.
- Updated docs to reflect new option, and provided an example.
- package.py uses context manager more effectively.
- Stage.__init__ has easier to understand method signature now.
- keep can be used to override the default behavior either to keep
the stage ALL the time or to delete the stage ALL the time.
- This reverts commit c5d9ee8924.
- merged too soon before
- reverting and fixing bugs now.

This does several things:
- Add `sbang`: a script to run scripts with long shebang lines.
- Documentation for `sbang` is in `bin/sbang`.
- Add an `sbang` hook that filters the `bin` directory after install
and modifies any scripts wtih shebangs that are too long to use
`sbang` instead.
- `sbang` is at the top level, so it should be runnable (not much we
can do if spack itself is too deep for shebang)
- `sbang`, when used as the interpreter, runs the *second* shebang
line it finds in a script.
- shoud fix issues with too long shebang paths.
- This moves var/spack/packages to var/spack/repos/builtin/packages.
- Packages that did not exist in the source branch, or were changed in
develop, were moved into var/spack/repos/builtin/packages as part of
the integration.

- Code simplification ignored case where exception was raised.
- If LockError was raised, read and write counts were incremented erroneously.
- updated lock test.
- llnl.util.lock now uses fcntl.lockf instead of flock
- purported to have more NFS compatibility.
- Added an extensive test case for locks.
- tests acquiring, releasing, upgrading, timeouts, shared, & exclusive cases.
