cffd5a3eb4 Use the BSD madvise() syscall implementation for Linux binary emulation,
instead of treating it as an unimplemented syscall. This appears to make
StarOffice 7.0 Linux binaries work according to submitter; also tested
with nvidia driver by submitter.

5002a60f9b Round of cleanups and enhancements. These include (in random order):
o  Introduce private types for use in linux syscalls for two reasons:
   1. establish type independence for ease in porting and,
   2. provide a visual queue as to which syscalls have proper
      prototypes to further cleanup the i386/alpha split.
   Linuxulator types are prefixed by 'l_'. void and char have not
   been "virtualized".

o  Provide dummy functions for all syscalls and remove dummy functions
   or implementations of truely obsolete syscalls.

o  Sanitize the shm*, sem* and msg* syscalls.

o  Make a first attempt to implement the linux_sysctl syscall. At this
   time it only returns one MIB (KERN_VERSION), but most importantly,
   it tells us when we need to add additional sysctls :-)

o  Bump the kenel version up to 2.4.2 (this is not the same as the
   KERN_VERSION MIB, BTW).

o  Implement new syscalls, of which most are specific to i386. Our
   syscall table is now up to date with Linux 2.4.2. Some highlights:
   -  Implement the 32-bit uid_t and gid_t bases syscalls.
   -  Implement a couple of 64-bit file size/offset bases syscalls.

o  Fix or improve numerous syscalls and prototypes.

o  Reduce style(9) violations while I'm here. Especially indentation
   inconsistencies within the same file are addressed. Re-indenting
   did not obfuscate actual changes to the extend that it could not
   be combined.

NOTE: I spend some time testing these changes and found that if there
      were regressions, they were not caused by these changes AFAICT.
      It was observed that installing a RH 7.1 runtime environment
      did make matters worse. Hangs and/or reboots have been observed
      with and without these changes, so when it failed to make life
      better in cases it doesn't look like it made it worse.

956d3333ca sigset_t change (part 4 of 5)
-----------------------------

The compatibility code and/or emulators have been updated:

iBCS2 now mostly uses the older syscalls. SVR4 now properly
handles all signals. This has been achieved by using the
new sigset_t throughout the emulator. The Linuxulator has
been severely updated. Internally the new Linux sigset_t is
made the default. These are then mapped to and from the
new FreeBSD sigset_t.

Also, rt_sigsuspend has been implemented in the Linuxulator.
Implementing this syscall basicly caused all this sigset_t
changing in the first place and the syscall has been used
throughout the change as a means for testing. It basicly is
too much work to undo the implementation so that it can
later be added again.

A special note on the use of sv_sigtbl and sv_sigsize in
struct sysentvec:
Every signal larger than sv_sigsize is not translated and is
passed on to the signal handler unmodified. Signals in the
range 1 upto and including sv_sigsize are translated.
The rationale is that only the system defined signals need to
be translated.

The emulators also have been updated so that the translation
tables are only indexed for valid (system defined) signals.
This change also fixes the translation bug already in the
SVR4 emulator.

And as long as we're here, rename some unimplemeted syscalls (linux_phys ->
linux_umount2, linux_vm86 -> linux_vm86old, linux_new_vm86 -> linux_vm86).

Change prototype for linux_newuname from `struct linux_newuname_t *' into
`struct linux_new_utsname *'. This change is reflected in linux.h and
linux_misc.c.

06ebbe77ed Implementation of linux_rt_sigaction and linux_rt_sigprocmask syscalls. Both
functions use the new sigset_t and sigaction_t which allows support for more
than 32 signals. Only the lower 32 signals are supported for now.

linux_rt_sigaction, linux_sigaction and linux_signal use linux_do_sigaction
to do the actual work. That way unnecessary redundancy is avoided. The same
has been done for linux_rt_sigprocmask and linux_sigprocmask. They call
linux_do_sigprocmask to do the actual work.

ecbb00a262 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
