By analysing objdump output some read only structures were found in
.data section. To help compiler further optimize code declare these
as const.

It looks like the "pos + plen > end" case was not clear enough for a
static analyzer to figure out that plen was being verified to not go
beyond the buffer. (CID 72687)

The payload lengths were not properly verified and the first check on
there being enough buffer for the header was practically ignored. The
second check for the full payload would catch length issues, but this is
only after the potential read beyond the buffer. (CID 72687)

This makes the implementation less likely to provide useful timing
information to potential attackers from comparisons of information
received from a remote device and private material known only by the
authorized devices.

It does not look like there is going to be any additional use for this
old build option that could be used to build the EAP-IKEv2 peer
implementation in a way that interoperates with the eap-ikev2.ccns.pl
project. Remove the workarounds that matches incorrect implementation in
that project to clean up implementation.

This commit adds a new wrapper, random_get_bytes(), that is currently
defined to use os_get_random() as is. The places using
random_get_bytes() depend on the returned value being strong random
number, i.e., something that is infeasible for external device to
figure out. These values are used either directly as a key or as
nonces/challenges that are used as input for key derivation or
authentication.
The remaining direct uses of os_get_random() do not need as strong
random numbers to function correctly.
In addition, start ordering header file includes to be in more
consistent order: system header files, src/utils, src/*, same
directory as the *.c file.
