This is to avoid parsing garbage past packet's actual end.
Also const-ize params to a few functions.

In commit
c4fb8c6a - fsck: do not use statics
not only statics were changed but also a couple of
statics-unrelated changes were made.
This included the handling of the child termination status
as follows:
- if (WIFEXITED(status))
- status = WEXITSTATUS(status);
- else if (WIFSIGNALED(status)) {
+ status = WEXITSTATUS(status);
+ if (WIFSIGNALED(status)) {
This is wrong, should have used a different variable to hold exit code.

trim() modifies the string in place if needed and returns a pointer to
the end of the resulting string. Update udhcp_str2optset() so it no
longer sets the value of 'val' to the return value of trim().

-t, -S and -G each take mandatory integer arguments. getopt32long()'s
option string syntax for this type of argument is 'c:+', however nsenter's
opt_str uses 'c+', which specifies two options 'c' and '+' which do not
take arguments. This means that giving a target PID causes nsenter to
exit and print the usage string:
# nsenter -t1 sh
nsenter: unrecognized option: 1
BusyBox v1.27.2 (2017-12-12 10:41:50 GMT) multi-call binary.
...
The long form options are also broken:
# nsenter --setuid=1000 --setgid=1000 sh
BusyBox v1.29.0.git (2018-05-04 13:56:49 UTC) multi-call binary.
...
`nsenter --target=<pid> sh` parses correctly and appears to work, but
<pid> is ignored and set to 0. This doesn't raise an error unless one
of the namespace arguments is also given:
# ./busybox_unstripped nsenter --target=42 sh
# exit
# ./busybox_unstripped nsenter -n --target=42 sh
BusyBox v1.29.0.git (2018-05-04 13:56:49 UTC) multi-call binary.
...
This has caused problems in a couple of places:

In nsenter from util-linux, the long version of the -n option is
--net=<path>. BusyBox's version expects --network=<path>, so scripts
and examples written for util-linux's version cause BusyBox's version
to exit with the usage message.
Confusingly, until commit 036585a911, the usage message erroneously
claimed that the long option was indeed called --net; after that commit
long options are not listed at all.

Commit 952d5a6024 (applets/install: accept more than one install
option) changed the way we handle install options: before that commit, a
missing install type would mean to install nothing; after, we would
iterate over options, so we would never notice there was a mising
option.
Fix that by introducing an explicit --none option to specify to install
nothing.

expand: Fix buffer overflow in expandmeta
The native version of expandmeta allocates a buffer that may be
overrun for two reasons. First of all the size is 1 byte too small
but this is normally hidden because the minimum size is rounded
up to 2048 bytes. Secondly, if the directory level is deep enough,
any buffer can be overrun.
This patch fixes both problems by calling realloc when necessary.
