fc34180cca Add "blocktest" test, for testing block drivers
The test is located in test/blocktest. It requires hand-editing of
its configuration, and is not part of any automated test set.

ff542f0b27 atl2: prevent compiler memory access misordering
While no problems have been observed in practice yet, modern compilers
may reorder memory access operations, and that could lead to problems
with memory-mapped I/O typically done by drivers. This patch prevents
any potentially problematic reordering by the compiler in the ATL2
driver.

In addition, this patch removes a number of gcc/clang warnings.

e1d867b686 ahci/libdriver: multithreading support
This patch adds support for executing multiple concurrent requests on
different devices on the same AHCI controller. The libdriver library
has been extended to include a generic multithreading interface, and
the AHCI driver has been extended to make use of this interface.

The original version of this code has been written by Arne Welzel.

0812293b47 procfs: fix for PID reuse between updates
In certain cases, a process ID may be reused between two lazy updates
of procfs's PID table. If the new associated process slot has a lower
index than the old one, this will trigger an assert in vtreefs, as the
new PID name entry is added before the old one is removed. This patch
fixes the problem by always first removing old PID name entries before
adding new ones.

Bug reported by Stephen Hatton.

823e42c3e3 Make AVFS deal intelligently with back calling FSes
PUFFS file systems need to make back calls for every operation we
send to them. Consequently, they cannot handle block reads and writes
themselves. Instead, the root file system has to do it (for now).

When the mount operation causes an FS to make a back call, AVFS now
concludes that every block read and write for that FS has to go
through the root file system.

203937456e Fix off-by-one errors and increase PATH_MAX to 1024
In some places it was assumed that PATH_MAX does not include a
terminating null character.

Increases PATH_MAX to 1024 to get in sync with NetBSD. Required some
rewriting in AVFS to keep memory usage low (the stack in use by a thread
is very small).
