MFC r310648:

style(9): clean up trailing whitespace

MFC r299710,r299711,r299763,r299783,r299811:

r299710:

Staticize global variables only used in bsnmpimport.c to fix
-Wmissing-variable-declarations warnings

r299711:

Fold two malloc + memset(.., 0, ..) calls into equivalent calloc calls

r299763:

Mute -Wstrlcpy-strlcat-size warning by using nitems with the size of the buffer

This is a no-op as the malloc above set the size of the buffer to the size used
below, but this keeps things consistent in case the malloc call changes somehow.

r299783:

Convert tok from enum tok to int32_t in function calls

get_token(..) returns int32_t, not enum tok, and in many cases tests for items
not in enum tok (e.g. '('). Make the typing consistent with get_token, which
includes a domino effect of changing enum tok to int32_t.

r299811:

Use strdup instead of malloc + strlcpy

Fix error messages on failure for calloc/strdup

MFC r298451,r298452,r298507,r298750:

r298451:

Don't use `entry` after free in the "already in lists" case

Return with 0 as it isn't an error.

CID: 1006085
Obtained from: Isilon OneFS (part of r493633)

r298452:

Don't try to free `string` (stack allocated char[])

Fix minor style with warnx call while in the neighborhood

CID: 1009683

r298507:

Fix looking for "UTC" at start of ptr by using strnmp instead of improperly
unrolled equivalent

CID: 1347118

r298750:

Use a better idiom for finding UTC prefixed timezones

Instead of copy-pasting the string literal for "UTC" 3 times and using
strlen, use a static char[3] buffer and sizeof(..).

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.
