bc09db942d Call biodone() in the bdev_strategy() error via a pointer. Decouples 
subr_devsw from VFS -- not that I/O buffers are _VFS_ entities -- and
eliminates the last weak alias from librump, which means things now
fully work on glibc (w/o LD_DYNAMIC_WEAK) and musl.

The whole code path is suspect anyway, since nothing prevents the device
from escaping after the lookup, suggesting that the whole error path
should be handled by the caller, but oh well.

984f14ab1c Permissions work better if you specify them in octal ... 
Also, do an explicit chmod of /tmp to account for cmask getting in the way.

4ae03c1815 - Split off PRU_ATTACH and PRU_DETACH logic into separate functions. 
- Replace malloc with kmem and eliminate M_PCB while here.
- Sprinkle more asserts.

42c8d67c49 Add a global vnode cache: 
- vcache_get() retrieves a referenced and initialised vnode / fs node pair.
- vcache_remove() removes a vnode / fs node pair from the cache.

On cache miss vcache_get() calls new vfs operation vfs_loadvnode() to
initialise a vnode / fs node pair.  This call is guaranteed exclusive,
no other thread will try to load this vnode / fs node pair.

Convert ufs/ext2fs, ufs/ffs and ufs/mfs to use this interface.

Remove now unused ufs/ufs_ihash

Discussed on tech-kern.

Welcome to 6.99.41

f7f79bc05e Eliminate weak symbols from rump kernel syscall handlers, part 4: 
Do not query system call handlers by using the rumpuser_dl_globalsym()
hypercall -- it will not work in environments which are not in control
of their own symbols (e.g. rumpuser-xen).  Instead, provide
rump_syscall_boot_establish(), which component constructors can use
to establish their non-modular syscalls.

8fa17e4756 scsitest is a SCSI target emulator used by one test, and has little 
reason to get installed.  Make the component private to the test using
it and obsolete the installed one.

IOW, rename sys/rump/dev/lib/libscsitest -> tests/dev/scsipi/libscsitest

e1b9adcc58 Make sleepq_wake() type void. The return value hasn't been used in 
almost 6 years.  Even if it were, returning an arbitrary lwp is a bit
of a wonky interface and can really work only when expected == 1.

d6454414fd Add a RUMP_USE_CTOR compile-time switch. If defined, use 
__attribute__((constructor)) to determine which rump kernel components
and kernel modules are linked into the rump kernel.  If not defined
(default), use the regular approach with link sets.

This option is aimed to fix problems with toolchains where using link
sets is not possible because the linker does not generate the requisite
__start/__stop symbols for the link set sections (e.g. GNU gold, OS X, ...).

Main benefit: rump_component_load() can now be called from an
early-running constructor since the routine doesn't need to allocate
memory.
