- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

this space.

- Whitespace cleanup while I'm at it

- Handle the case where pltgot[1] is 64 bit.
- use 'ifdef __mips_n64' instead of 'ELFSIZE == 64' to detect 64 bit compile.
