Eelco Dolstra 224b56f10e Move creation of the temp roots file into its own function 
This also moves the file handle into its own Sync object so we're not
holding the _state while acquiring the file lock. There was no real
deadlock risk here since locking a newly created file cannot block,
but it's still a bit nicer.

Release shared lock before acquiring exclusive lock 
In principle, this should avoid deadlocks where two instances of Nix are
holding a shared lock on big-lock and are both waiting to get an
exclusive lock.

However, it seems like `flock(2)` is supposed to do this automatically,
so it's not clear whether this is actually where the problem comes from.

Eelco Dolstra c164d304f3 nix develop: Set personality 
This makes 'nix develop' set the Linux personality in the same way
that the actual build does, allowing a command like 'nix develop
nix#devShells.i686-linux.default' on x86_64-linux to work correctly.

rski d034ed1891 src/libstore: Print the reason opening the DB failed 
Without this, the error is lost, and it makes for a hard to debug
situation. Also remove some of the busyness inside the sqlite_open_v2
args.

The errcode returned is not the extended one. The only way to make open
return an extended code, would be to add SQLITE_OPEN_EXRESCODE to the
flags. In the future it might be worth making this change,
which would also simplify the existing SQLiteError code.

Robert Hensing c965f35de7 Improve sqlite error messages 
They did not include the detailed error message, losing essential
information for troubleshooting.

Example message:

    warning: creating statement 'insert or rplace into NARs(cache, hashPart, namePart, url, compression, fileHash, fileSize, narHash, narSize, refs, deriver, sigs, ca, timestamp, present) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, 1)': at offset 10: SQL logic error, near "rplace": syntax error (in '/tmp/nix-shell.grQ6f7/nix-test/tests/binary-cache/test-home/.cache/nix/binary-cache-v6.sqlite')

It's not the best example; more important information will be in
the message for e.g. a constraint violation.

I don't see why this specific error is printed as a warning, but
that's for another commit.

Allow disabling build users by unsetting build-users-group 
Unsetting `build-users-group` (without `auto-allocate-uids` enabled)
gives the following error:

```
src/libstore/lock.cc:25: static std::unique_ptr<nix::UserLock> nix::SimpleUserLock::acquire(): Assertion `settings.buildUsersGroup != ""' failed.
```

Fix the logic in `useBuildUsers` and document the default value
for `build-users-group`.
