Remove init of proto, header field, expert info and subtree variables.
This will reduces the binary size by approximate 1266320 bytes due to
using .bss to zero-initialize the fields.
The conversion is done using the tools/convert-proto-init.py script.
Implement little endian support for tvb_get_bits family of functions.
The big/little endian refers to bit numbering within an octet. In big
endian, the most significant bit is considered bit 0, while in little
endian the least significant bit is considered bit 0.
Add encoding parameters to proto tree bits format family functions.
Specify ENC_BIG_ENDIAN in all dissectors using these functions except in
USB HID that requires ENC_LITTLE_ENDIAN to work correctly.
When formatting bits values, always display most significant bit on the
leftmost position regardless of the encoding. This results in no gaps
between octets and makes the displayed value comprehensible.
Close#4478Fix#17014
Automated find/replace of wmem_packet_scope() with pinfo->pool in all
files where it didn't cause a build failure.
I also tweaked a few of the docs which got caught up.
Most of the time, the return value tells us nothing useful, as we've
already decided that we're perfectly willing to live with string
truncation. Hopefully this keeps Coverity from whining that those
routines could return an error code (NARRATOR: They don't) and thus that
we're ignoring the possibility of failure (as indicated, we've already
decided that we can live with string truncation, so truncation is *NOT*
a failure).
The static arrays are supposed to be arrays of const pointers to int,
not arrays of non-const pointers to const int.
Fixing that means some bugs (scribbling on what's *supposed* to be a
const array) will be caught (see packet-ieee80211-radiotap.c for
examples, the first of which inspired this change and the second of
which was discovered while testing compiles with this change), and
removes the need for some annoying casts.
Also make some of those arrays static while we're at it.
Update documentation and dissector-generator tools.

Length calculations updating "remaining datagram size" for fragmented
6LoWPAN packets with NHC headers were incorrect if there was any elided
option padding.
The current header's unpadded length was subtracted from dgram_size,
when it should have been the padded length - the datagram size is
uncompressed IPv6.
This meant the final nhdr_list entry created to represent the remaining
payload would have its "reported" field too large. Most visible result
of this was that the IPv6 payload length written into the packet by
lowpan_reassemble_ipv6() was too large.
Error probably went unnoticed because the most typical 6LoWPAN options
don't need padding - the RPL option is 6 bytes, and the MPL option is 6
bytes if using 16-bit seeds, making the HbH extension header an aligned
8 bytes.
