  geom_part: Check number of GPT entries and size of GPT entry

Current specification does not have upper limit of the number of
partition entries and the size of partition entry. In
799eac8c3df597179bbb3b078362f3ff03993a1a Andrey V. Elsukov introduced a
limit maximum number of GPT entries to 4k, but that is for write routine
(gpart create) only. When attaching disks that have large number of GPT
entries exceeding the limit, or disks with large size of partition
entry, it is still possible to exhaust kernel memory.

1. Reuse the limit of the maximum number of partition entries.
2. Limit the maximum size of GPT entry to 1k.

In current specification (2.10) the size of GPT entry is 128 *
2^n while n >= 0, and the size - 128 is reserved. 1k should be
sufficient enough for foreseen future.

  geom_part: Fix potential integer overflow when checking size of the table

`hdr_entries` and `hdr_entsz` are both uint32_t as defined in UEFI spec.
Current spec does not have upper limit of the number of partition
entries and the size of partition entry, it is potential that malicious
or corrupted GPT header read from untrusted source contains large size of
entry number or size.

  geom_linux_lvm: Check the offset of physical volume header

The LVM label is stored on any of the first four sectors, and the
PV (physical volume) header is stored within the same sector following
the LVM label. The current implementation does not fully check the
offset of PV header, when attaching a bad formatted LVM PV the kernel
may crash due to out-of-bounds memory read.

  net: Remove vlan metadata on pcp / vlan encapsulation

For oubound traffic, the flag M_VLANTAG is set in mbuf packet header to
indicate the underlaying interface do hardware VLAN tag insertion if
capable, otherwise the net stack will do 802.1Q encapsulation instead.

Commit 868aabb4708d introduced per-flow priority which set the priority ID
in the mbuf packet header. There's a corner case that when the driver is
disabled to do hardware VLAN tag insertion, and the net stack do 802.1Q
encapsulation, then it will result double tagged packets if the driver do
not check the enabled capability (hardware VLAN tag insertion).

Unfortunately some drivers, currently known cxgbe(4) re(4) ure(4) igc(4)
and vmx(4), have this issue. From a quick review for other interface
drivers I believe a lot more drivers have the same issue. It makes more
sense to fix in net stack than to try to change every single driver.

This vnet loader tunable is defined with SYSCTL_PROC, thus will not be
initialized by kernel on vnet creating and will always have the default
value TCP_FASTOPEN_CCACHE_BUCKET_LIMIT_DEFAULT.

Fix by fetching the value from the corresponding kernel environment during
vnet constructing.
