patches/RELENG_8_3: uhso.diff removal

This patch wasn't enabled for builds enabled anyway. A more recent
version is part of FreeBSD 8.3, and our patch was likely integrated
with the following commit:

    Add a driver by Fredrik Lindberg for Option HSDPA USB devices. These
    differ from standard 3G wireless units by supplying a raw IP/IPv6
    endpoint rather than using PPP over serial. uhsoctl(1) is used to
    initiate and close the WAN connection.
patches/RELENG_8_3: uhso.c.diff removal

This patch hasn't been enabled back to pfSense based on RELENG_8_0 but
added then for unattendedd amd64 builds according to initial commit:

Author: sullrich <sullrich@pfsense.org>
Date:   Tue Dec 8 01:12:14 2009 -0500

    Allow amd64 builds to happen unattended

Since we have unattended amd64 builds working for longer time,
removing this patch should be safe.
patches/RELENG_8_3: various_8.2_fixes.diff shrink

This patch wasn't enabled for our builds anyway. The hunks that
have been identified to be 1:1 part of 8.3 have been removed.

The remaining hunk patches diverged code but it isn't yet certain
if our modification would be still required.
patches/RELENG_8_3: bce_head.tgz removal

This patch archive wasn't enabled for builds anyway.
The bce(4) module in 8.3 is more recent than what this
patch contained.

The missing ids for 5716's is due to being virtually
same as 5709's per:

    MFC r226123:
      BCE_MISC_ID register of BCM5716 returns the same id of BCM5709 so
      remove explicit checks for BCM5716.
      The BCM5709 and BCM5716 chips are virtually indistinguishable by
      software except for the PCI device ID.  The two chips differ in
      that BCM5709 supports TCP/IP and iSCSI offload in Windows while
      the BCM5716 doesn't.
      While I'm here remove now unused definition of BCE_CHIP_NUM_5716
      and BCE_CHIP_ID_5716_C0
patches/RELENG_8_3: ng_tcpmss.diff removal

This patch archive wasn't enabled for builds anyway. Checking history
shows this patch was introduced into builds based on FreeBSD 8.1, but
within then later been disabled because of regressions caused by it.

pfSense issue #1336, comment 14:

"[...] the patch had to be backed out for now - it appears to have been
negatively impacting pppoe on amd64.

This
patches/RELENG_8_3: bce_performance.diff removal

This patch wasn't enabled for builds anyway. The patch has been
disabled initially because FreeBSD 9.0 added a tunable for this.

The tunable required is (very likely as it seems) present in 8.3
and thus can be removed now.
