netgraph: provide separate malloc type for nodes that are missing it

The kernel option NG_SEPARATE_MALLOC helps to debug memory leaks in
netgraph(4). Several nodes were missing the support.

Fix packet cbs/ebs conversion.

Each packet is counted as 128 bytes by the code, not 125. Not sure
what I was thinking about here 14 years ago. May be just a typo.

sys: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

sys/netgraph: spelling fixes in comments.

No functional change.

Node constructor methods are supposed to be called in syscall
context always. Convert nodes to consistently use M_WAITOK flag
for memory allocation.

Switch from timeval to bintime, to use 1/(2^20) of seconds instead of
microseconds. It allows to use bit shifts instead of some heavy 64bit
mul/div math operations.

Add option to set packets per second limits instead of default
bits per second ones.

Add missing ng_uncallout() on node shutdown.
