Rather than reuse XID's on retransmissions, always use a unique XID.
Either behaviour is permitted by rfc2131. Debugging the dhcp client
in the presence of multiple dhcp servers with significant packet loss
in the network is much easier if we don't unnecessarily reuse request
identifiers.

The example entropy_source implementation should write entropy to the
output buffer rather than to the context pointer which in this example
happens to be NULL.
Take the opportunity to reorganize the entropy_source to use all of
the entropy provided by a call to sys_rand32_get() rather than just
1/4 of it.
The entropy_source() callback from mbedtls is given a maximum amount
of entropy to return, rather than a minimum amount. Hence it makes
more sense to deliver exactly one chunk (32 bits) of entropy from the
call to sys_rand32_get() per call and let the mbedtls entropy handler
worry about how much entropy we actually need to collect (ie the threshold).

Currently CONFIG_OMIT_FRAME_POINTER is a boolean and defaults to N,
which increases code size. This is intended to improve debugability
but on many architectures the use of this option does not actually
compromise debugging. Further the compiler already knows whether or not
omitting the frame pointer is harmful to debugging and its defaults
are selected accordingly.
By making this choice optional we can have a sane default on *all*
architectures by letting the compiler decide for us.
This patch significantly improves the default code generation on
arm (thumb), nios2 and arc. The benefit looks to be about between 5%
and 10% code size reduction depending upon architecture). x86 is
unaffected.
