4e6dd9c576 ping: add stop function
ping in raw mode does some set up and sets timeout, but clean
up procedure is missing. That is needed for case if PING_RESULT() macro
is used for application exit.

Also implement stop functionality when using sockets.
Running ping is stopped when calling ping_init() again.

1a5dffb931 win32: pcapif: ensure we can run with npcap as well
By default, npcap keeps its DLLs not in system32 but in system32/npcap.
To load DLLs from there, mark them as "delay load DLLs" and adjust the
DLL search path before using/loading them.

c2f9244137 test/fuzz: Fix use of htons vs. ntohs
Although ntohs and htons perform equivalent operations (a byte swap on
little-endian platforms), their semantic roles (as implied by the names)
are different.

In fuzz_common.c, we get integers from simulated network packages, and
convert them for host CPU use, so ntohs is the right variant to use.

911da26f96 test/fuzz: Fix CC default value in makefile
Unfortunately, CC ?= afl-gcc doesn't work. This is because CC has a
default value (of "cc"), and the ?= operator only assigns a value if the
variable previously had none. "make" currently compiles with cc.

In this patch, I implemented the more elaborate way to achieve what was
probably intended: "make" will use afl-gcc now, and "make CC=foo" will
compile with "foo".

5231c8da23 dhcp: Enable custom config for timeouts, thresholds, backoff time
Enables to configure:
* DHCP_COARSE_TIMER_SECS
* if DHCP_DEFINE_CUSTOM_TIMEOUTS defined these addtional options are
available:
  - DHCP_CALC_TIMEOUT_FROM_OFFERED_T0_LEASE to adjust the t0 lease timeout from the offered value
  - DHCP_CALC_TIMEOUT_FROM_OFFERED_T1_RENEW same for t1 renew
  - DHCP_CALC_TIMEOUT_FROM_OFFERED_T2_REBIND same for t2 rebind
  - DHCP_NEXT_TIMEOUT_THRESHOLD to adjust the period of the next timeout
  - DHCP_REQUEST_BACKOFF_SEQUENCE to adjust back-off times based on DHCP
request attempts
Also updates timeout type from u16 to u32 - eps useful when DHCP_COARSE_TIMER_SECS is a smaller number

A fuzzer may generate big packets, and it will interpret assertion
failures as bugs. Instead of asserting that the packet size is
