ppc64 build framework

Add symbol entries for the missing signal functions for the benefit of
autoconf. Autoconf compiles simple programs like:
char symbol();
int main() { return symbol(); }
To check if the symbol is present. This makes it happy.
Another way our symbol renaming breaks things.
This fixes gdb native build, which does not find sigprocmask otherwise
and fails to build because it finds pthread_sigmask() and not sigprocmask()!

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.
