After a call to pthread_create(), it is indeterminate which thread the
caller or the new thread will next execute. Synchronize with the new
thread and allow it to initialize (and print to console, before the
print can potentially interfere with other prints) before proceeding.

Now that HOOK_INIT hooks are called from a task switching context, most
calls to task_start_called() should no longer be needed. This commit
removes them.

Policies give a convenient place to hook into the queue operations

Previously there was no way to remove multiple units at a time
from the queue, and the queue was wasting an entry to disambiguate
full from empty. There was also no way to get the free entry
count from the queue, only the ability to query if it was above
a required amount. The queue was also storing its constant
compile time configuration as well as its dynamic state in the
same structure. This wasted RAM on configuration information
that doesn't change.
This refactor fixes these issues, making the queue suitable for
use in the new USART stream driver.

Now that we handle all UART input from interrupt context, we shouldn't
need to guard input buffer with mutex lock. Removing the stale TODO
comment and adding an assertion to ensure this argument is correct.

Currently emulator UART input/output are processed in various context,
including UART thread, individual tasks, and tests. By moving the
processing to interrupt context, the way it works resemble real chips
more. Also, this provides a cleaner cut between emulated UART device and
UART processing code.

This provides us a way to inject interrupts during a test. If a test has
interrupt_generator() defined, it will run in a separate thread. The
generator can then trigger interrupts when it decides to. The current
running task is suspended while emulator is executing ISR.
Also fixes a bug that tasks run without scheduler notifying them during
emulator start-up.

Both of these are included via common.h, which is in turn included by
most other header files. Directly including board.h or config.h is
redundant and discouraged.
No code changes, just removing #includes.
This is in preparation for making a top-level config.h file, but that
change will be easier to review if it doesn't touch as many files.
