2941a7af6e Include some headers to make rump_syscalls.h self-contained. 
(not strictly correct wrt portability, but there are bigger fish
to saltgrill in that area)

0ef29cbdba Rename rump argument marshalling structure variable to "callarg" to 
avoid collision with system calls which use "arg".

b50bd8632e Instead of linking rump system call entry points directly to the 
backend, perform all calls through a syscall table.  This makes it
possible to make system calls to non-local rump kernels.
(requires a bit support code.  it's written but quite messy currently)

06abc8c3f9 Remove debug print -- this is what happens when there's several 
hours between implementation and commit.

c7e5a8be4e Remove the "int *error" parameter from rump syscalls. Instead use 
rumpuser_seterrno() to set the errno for the caller.  This makes
the difference between real and rump syscalls way less intrusive
in calling code.

the rump_syscalls.h interface from inside the rump kernel.

a9a2ce837b Convert the syscalls.master to a format from which it is easier 
to parse and generate the compat name and basename (e.g. __stat50
and stat).  Use this to autogenerate __RENAME()'s to the rump_syscalls
header so that they can be called e.g. rump_sys_socket() instead
of rump_sys___socket30().

3a64aae825 Fix previous: weak symbols work so much better if they are exported 
from the object as weak symbols...

There's also something to be said about "cosmetic" tweaks after
testing, but I do think I'll bother.

7cb9e72bbb Avoid using \$ in an awk script. Instead, store '$NetBSD$' 
in an awk variable and interpolate it where needed.

Based on the patch by Martin Husemann in PR 38766.

30abe39468 - Retire SYCALL_MPSAFE. With the exceptions of darwin and irix emulations, 
all system calls are now MPSAFE.

d5bb355fe9 Handle rumpcalls/rumpcallshdr differently by always defining a default 
value, which can be overwritten with syscalls.conf defines (just like
sys_nosys).

This fix a problem where rump awk variables are set to 0 value,
leading to the creation of an unexpected file with that name.

ok by pooka.

f2976c3905 Generate syscalls entry points which can be called directly without 
going through a syscall trap.  These are currently useful for rumps.
As all the standard syscalls are not compiled into librump, mark
relevant ones with RUMP in syscalls.master.  To do e.g. a mkdir
"system call" from a rump, one would call

  rump_sys_mkdir("/dir", mode, &eval);

where the last value represents something to store errno into.

fcf1e44d76 Do not hardcode sys_stub to the string "sys_nosys" for the not ignored 
case. Just use the corresponding variable instead, to allow emulation
to use their own defined value.

7e2790cf6f Convert all the system call entry points from: 
int foo(struct lwp *l, void *v, register_t *retval)
to:
    int foo(struct lwp *l, const struct foo_args *uap, register_t *retval)
Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).
98% done by automated scripts.

060456b651 Couple of changes: 
* Make the syscallnames[] table const.
* Add a separator between the #include section and the syscalls section, so
  that #if/#else/#endif can be handled differently in the two.
* Add support for rounding up the size of the sysent table.
