use memcpy in bf_copy() instead of copy word by word in for loop

Realloc doesn't init - ensure a newly-allocated word is inited.

Use FRR mem api instead of raw realloc() in bitfield module.

*: convert to SPDX License identifiers

Add a function to copy a bitfield_t structure.
Add a ‘void *’ to ‘word_t *’ converstion in bf_init() to avoid the
following error:
> ./lib/bitfield.h: In function ‘bf_copy’:
> ./lib/bitfield.h:75:12: error: request for implicit conversion from ‘void *’ to ‘word_t *’ {aka ‘unsigned int *’} not permitted in C++ [-Werror=c++-compat]
> (v).data = XCALLOC(MTYPE_BITFIELD, ((v).m * sizeof(word_t))); \
> ^
> ./lib/bitfield.h:278:2: note: in expansion of macro ‘bf_init’
> bf_init(dst, WORD_SIZE * (src.m - 1));
> ^~~~~~~

Done with a combination of regex'ing and banging my head against a wall.

- double the size of each new chunk request from zebra
- use bitfields to track label allocations in a chunk
- When allocating:
- skip chunks with no free labels
- search biggest chunks first
- start search in chunk where last search ended
- Improve API documentation in comments (bgp_lp_get() and callback)
- Tweak formatting of "show bgp labelpool chunks"
- Add test features (compiled conditionally on BGP_LABELPOOL_ENABLE_TESTS)

it is handy to be able to see allocated bitfields in the show
memory output.

New macros have been added for the following -
1. to efficiently iterate and execute functions on already set bits
2. to check if a bit is in use
3. to check if a bitfield has been initialized (this is to safetly
handle cases where the bitfield is freed and re-allocated).
4. to check if two bitfields have the same bits set

Added APIs to:
a) pre-assign 0th bit in the bitfield
b) free 0th bit in the bitfield
c) free the allocated bitfield data

The FSF's address changed, and we had a mixture of comment styles for
the GPL file header. (The style with * at the beginning won out with
580 to 141 in existing files.)
Note: I've intentionally left intact other "variations" of the copyright
header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

These files were submitted by Cumulus but did
not properly setup the licensing of them.
This fixes that issue.
