d4db6826f2 No specific called "exec(3)", so move primary manpage to a name which 
does exist -- execv(3).  Still call this a family but without "Nm".
Adjust Xr in various pages to refer to the precise function used
rather than the family, in most cases the semantics of execve(2) are
being referenced, so change the Xr.

df69c215c7 When system calls indicate an error they return -1, not some arbitrary 
value < 0.  errno is only updated in this case.  Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

59133b9f84 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.

815ff53b8d handle fallout of moving the address maps to RBT code. 
because userland doesnt have subr_tree, and the tree traversal in
this file is simple, this inlines the logic that the functions in
the kernel do.

1dd3716cfc Make amaps use less kernel memory (2nd try) 
The original diff would crash at least i386 and powerpc, as spotted by
guenther@ The reason was an incorrect use of sizeof in amap_lookups().

Confirmation that powerpc works by mpi@ and mglocker@

"throw it in" deraadt@

Original commit message:

This is achieved by grouping amap slots into chunks that are allocated
on-demand by pool(9). Endless "fltamapcopy" loops because of kmem
shortage should be solved now. The kmem savings are also important to later
enable vmm(4) to use larged shared memory mappings for guest VM RAM.

This adapts libkvm also because the amap structure layout has changed.
