remove prototypes with no matching function

A few fixes for kvm_getargv(3)/kvm_getenv(3):

1. Most notable: this splits argv buffer into argv-specific one
and environ-specific one. This makes ps -eww totally happy.

2. realloc() usage in kvm_argv() is now ENOMEM-prone.

3. The "int off" changed to "ptrdiff_t off", as it should be.

Add Symbols.map to explicitly define the ABIs, hiding linker defined symbols.
Use hidden aliases for internal invocations of exported symbols to avoid PLT.

add kvm_realloc() as a private function.

Apply reallocarray() idiom.

Mark internal symbols as hidden. This removes symbols from the ABI,
albeit ones no one should be using, so major bump the shlib.

_kvm_syserr() is printf-like too

Prep for hidden visibility: move the vnode/file related function
declarations, including _kvm_getftype(), into a new header, kvm_file.h,
so that we don't have to pull <sys/vnode.h> into all the .c files. No
more extern function declaration in .c files.

ok millert@

Apply format __attribute__ to _kvm_err() and fix the errors that it detects.
Treat failure to KREAD teh pcredd or ucreds to be errors insteading of
continuing with bogus data.

- add UNIX-domain socket info to struct kinfo_file2
- convert netstat from kvm_getfiles() to kvm_getfile2() using that
- delete kvm_getfiles() and KERN_FILE as no longer used (bump libkvm's major)
- rename kvm_getfile2() to kvm_getfiles(), kinfo_file2 to kinfo_file
and KERN_FILE2 to KERN_FILE.

Replace the old, broken KERN_PROC ABI and its matching functions
in libkvm with the stable-ABI versions that are currently named
KERN_PROC2, kvm_get{proc,argv,envv}2(). The latter names and symbols
will continue to be supported for a few releases.

Committing now that they ports people have had a couple releases
to update pkgs that usd the old functions

the comment is right, this can indeed go away.
it's unused inside libkvm, and nothing else is allowed to use it.

ok guenther@ "sure" deraadt@

Install ntfs includes and add libkvm (fstat) support. ntfs bits
adapted from NetBSD fstat. OK deraadt@

Move KREAD define to kvm_private.h

Split out cd9660 bits into their own .c file to avoid #define collisions
with ufs and add also udf support. OK miod@

Add kvm_getfile2 which uses KERN_FILE2 when possible, falling
back on kmem grovelling for non-live kernels. OK deraadt@

careful cleanup following advice from lint. be very very very careful
with sprinkling in size_t!

for some of internal functions use paddr_t where phys addr is intended insteadd of u_long; miod@ ok

Implement kvm_getproc2(), kvm_getargv2() and kvm_getenvv2() that use
the KERN_PROC2 sysctl. Based on changes from NetBSD but uses our
own kvm_arg_sysctl().

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

Add a flag - KVM_NO_FILES which tells kvm_openfiles to not
open any files, just return an kvm handle that we can use to some
of the functions.

Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.

Convert lseek/{read,write} pairs into pread and pwrite.
