launch_server tests: fix gcc2 build

The launch daemon tests consist of two parts: one unit test and one
set of "libbe_test" executables. These share some sources from the
launch daemon source directory, but use different compiler flags.

Due to the way we generate object files, the .o files for both variants
end up overwriting each other since they are generated in the same
directory.

There is also some confusion on compiler flags, since some flags are
applied globally to the directory and confuse one or the other of the
two targets.

To avoid this, move the test binaries to a subdirectory separate from
the unit tests.

launch_daemon: Added basic logging facility

* The daemon now stores many events in am internal log.
* You can use "launch_roster log" to retrieve it.

Added simple test_launch_daemon.

* Expects its config files in /boot/home/test_launch.
* Uses standard I/O, and is always in user mode.
* Also added test_launch_roster command that is able to talk to the test
server like it does to the real thing.

Build: Add architecture rule for libshared.a.

- As suggested by Ingo, add libshared.a to the architecture name map.
This allows it to be linked by its short name like other frequently
used libraries.
- Adjust all Jamfiles referencing the lib accordingly.

Fix unittests build.

launch_daemon: "file_exists" now resolves $HOME, and '~'.

launch_daemon: Added events parsing.

* Including tests, also for the environment parsing.

launch_daemon: Added condition tests.

launch_daemon: Started working on condition parsing.

* Moved related test code from DriverSettingsMessageAdapterTest to the
SettingsParser class.
* Added SettingsParserTest class -- most tests already succeed, but not
all; support for the flattened "not" is not working yet.
