mknod(2) automatically defaults to S_IFREG if not given an explicit
file type, so pseudo should too. Otherwise, GNU tar can (for some
reason, it mostly does this when extracting xattrs?) invoke mknod
instead of open with O_CREAT to create a file, and just provide the
permission bits, and pseudo creates a "weird file" with no type bits
in the database, which is unhelpful.

There's some changes to allow things to work even if umask is 0700;
originally this was just regarded as a broken state, but it became
necessary to fix it in order for the xattrdb code to work, only the
fix could result in files having a raw filesystem mode that lacked
execute bits it should have had.

We used to rely on filesystem operations to apply the umask when
appropriate, but when we started masking out 022, that stopped working.
Start watching umask.

the 0100 bit for directories. The reason is that otherwise we create
plain files which are 0700 on disk, which means they're non-zero &0111,
which breaks euidaccess(X_OK).

This is a spiffied-up rebase of a bunch of intermediate changes, presented
as a whole because it is, surprisingly, less confusing that way. The basic
idea is to separate the guts code into categories ranging from generic
stuff that can be the same everywhere and specific variants. The big scary
one is the Darwin support, which actually seems to run okay on 64-bit OS X
10.6. (No other variants were tested.) The other example given is support
for the old clone() syscall on RHEL 4, which affects some wrlinux use cases.
There's a few minor cleanup bits here, such as a function with inconsistent
calling conventions, but nothing really exciting.
