- 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.

Fix incorrect KASSERTs in xlpge

Fix for crash in Netlogic XLP network accelerator driver when invariants
are enabled - use correct the condition for KASSERT.

Little-endian and other fixes for Broadcom XLP network driver

The changes are:
- the microcore code loaded into the NAE has to be byteswapped
in LE
- the descriptors in memory for a P2P NAE descriptor has to be
byteswapped in LE
- the m_data pointer is already cacheline aligned, so the
unnecessary m_adj to cacheline size can be removed
- fix mask used to obtain physical address from the Tx freeback
descriptor
- fix a compile error in code under #ifdef
