c7fbafe1ad VFS: remove FP_BLOCKED_ON_DOPEN
These days, DEV_OPEN calls to character drivers block the calling
thread until completion or failure, and thus never return SUSPEND to
the caller. The same already applied to BDEV_OPEN calls to block
drivers. It has thus become impossible for a process to enter a state
of being blocked on a device open call.

There is currently no support for restarting device open calls to
restarted character drivers. This support was present in the _DOPEN
logic, but was already no longer triggering. In the future, this case
should be handled by the thread performing the open request.

784cdd4d07 PFS: remember request information for IOCTLs
Not doing so caused PFS to commit protocol violations by relying on
stale information when sending replies. This stale information always
happened to be correct, which is why the problem went unnoticed.

6331e8f845 Retire the synchronous character driver protocol
- change all sync char drivers into async drivers;
- retire support for the sync protocol in libchardev;
- remove async dev style, as this is now the default;
- remove dev_status from VFS;
- clean up now-unused protocol messages.

97172a1db0 Sync char protocol: add nonblocking transfer flag
The async char protocol already has this, so this patch closes the
gap between the two protocols a bit. Support for this flag has been
added to all sync char drivers that support CANCEL at all.

The LOG driver was already using the asynchronous protocol, but it
did not support the nonblocking transfer flag. This has been fixed
as well.

a75c47e5ac VFS: set w_drv_sendrec only when needed
As with w_task, this ensures that the field remains cleared if it is
not used. Without this, worker_stop could mistakenly identify a thread
as talking to a device driver rather than a (crashed) file server.

7d02ecdbb4 VFS: set w_task only when needed
It was always set, but not always cleared, when talking to asynchronous
drivers. This could cause erratic behavior upon a driver crash.

Normally, a worker thread's w_task field is set when it's about to
communicate with a driver or FS. Then upon receiving a reply we can
do sanity checks (that the thread we want to wake up was actually
waiting for a reply). Also, when a driver/FS crashes, we can identify
which worker threads were talking to the crashed endpoint and handle
the error gracefully.

Asynchronous drivers are a bit special, though. In most cases, the
sender of the request is not interested in the reply (the sender was
suspended and only wants to know whether the request was successfully
caried out or not). However, the open request is special, as the reply
carries information needed by the sender. This is the only request
where a worker thread actually yields and waits for the result. This is
also the only case where we're interested in setting w_task for
asynchronous drivers.

cfd3379bb1 Removing CSU patches
* Removed startup code patches in lib/csu regarding kernel to userland
   ABI.

 * Aligned stack layout on NetBSD stack layout.

 * Generate valid stack pointers instead of offsets by taking into account
   _minix_kerninfo->kinfo->user_sp.

 * Refactored stack generation, by moving part of execve in two
   functions {minix_stack_params(), minix_stack_fill()} and using them
   in execve(), rs and vm.

 * Changed load offset of rtld (ld.so) to:
      execi.args.stack_high - execi.args.stack_size - 0xa00000
   which is 10MB below the main executable stack.

cc810ee4d9 VFS/FS: replace protocol version with flag field
The main motivation for this change is that only Loris supports
multithreading, and Loris supports dynamic thread allocation, so the
number of supported threads can be implemented as a bit flag (i.e.,
either 1 or "at least as many as VFS has"). The ABI break obviates the
need to support file system versioning at this time, and several
other aspects are better implemented as flags as well. Other changes:

- replace peek/bpeek test upon mount with FS flag as well;
- mark libsffs as 64-bit file size capable;
- remove old (3.2.1) getdents support.

- align mount flags field with NetBSD's, splitting out service flags
  which are not to be passed to VFS;
- remove limitation of mount ABI to 16-byte labels, so that labels
  can be made larger in the future;
- introduce new m11 message union type for mount(2) as side effect.

744378194d Alignement on netbsd types, part 1
The following types are modified (old -> new):
 * _BSD_USECONDS_T_ int       -> unsigned int
 * __socklen_t      __int32_t -> __uint32_t
 * blksize_t        uint32_t  -> int32_t
 * rlim_t           uint32_t  -> uint64_t
On ARM:
 * _BSD_CLOCK_T_    int       -> unsigned int
On Intel:
 * _BSD_CLOCK_T_    int       -> unsigned long

bin/cat is also updated in order to fix warnings.

_BSD_TIMER_T_ has still to be aligned.

We currently have a few of the POSIX tests failing because filemmap
is enabled by default. The working assumption is that these program
pass a pointer to the file server that points to a not yet loaded
data segment. When the file server tries to access that data it
therefore generates a pagefault and a call to itself it can not
handle because it is unable to first return the current call.
