If ratp_establish() fails we would be accessing the ratp_internal

xfuncs: fix format specifier in pr_emerg call ...

xfuncs: Be more informative when out of memory panic occurs ...

When one of the xfuncs panics we can be a bit more informative. We
can at least print the amount of bytes we wanted to allocate and
how much memory we have left.

libgen: implement posix_basename ...

There are two different versions of basename(): The GNU version and the
POSIX version. The GNU version never modifies its argument and returns
the empty string when path has a trailing slash, and in particular also
when it is "/". The POSIX version modifies its argument and thus works
properly with strings which have a trailing "/".

lib/strtox: remove unnecessary islower() ...

toupper() does the right thing, no need to test for islower()
beforehand, so

islower(*cp) ? toupper(*cp) : *cp

can be simplified to:

toupper(*cp)

param: remove unnecessary device_d * argument ...

param: make parameter functions more consistent ...

This patch creates a consitent set of device parameter functions.

With this we have: dev_add_param_<type><access>

"type" is one of: int32, uint32, int64, uint64, string, mac, ipv4, enum, bitmask
The improvement here is that we now can exactly specify the width of the
int type parameters and also correctly distinguish between signed and
unsigned variables which means that a variable no longer ends up with
INT_MAX when it's assigned -1.

"access" can be empty for regular read/write parameter, "_ro" for readonly
parameters which get their value from a variable pointer in the
background or "_fixed" for parameters which are set to a fixed value
(without a pointer in the background).

Some more exotic types are not (yet) implemented, like
dev_add_param_ip_ro.

parameter: Give device parameters types ...

This adds a variable type enum and adds this to the device parameters.
This information gives the user a hint which values a parameter expects
and also helps to organize the parameters better internally.

lib: random: add get_crypto_bytes interface and use HWRNG if posssible ...

For crypto applications we need to use some thing else as PRNG.
So provide get_crypto_bytes() and use HWRNG as main source.
PRNG is allowed as fallback if user decided to configure it so.
