Fix a compile warning if we build using int types defined to match the
compiler. We get the following warnings:

This reverts commit 25fb2302f1.
The bluetooth l2cap code was using these errno values but changed to
using more standard EPERM instead, so lets remove the defines since
nothing uses them.

Some third-party components include this file without really needing
any symbols from it. Presence of this file allows to build them
against minimal libc, whereas previously they forced Newlib.

Placing it at sys/fcntl.h was due to mimicking internal newlib's
layout, but what we need is this file at the standard location,
for reuse.

Extended ring buffer to allow storing raw bytes in it. API has been
extended keeping 'data item' mode untouched.
Signed-off-by: Krzysztof Chruscinski <krzysztof.chruscinski@nordicsemi.no>
Deprecate API prefixed with sys_ring_buf_ and rename it
to ring_buf_item_ since this API is not a typical ring buffer
but ring buffer of data items (metadata + 32bit words).

For read/write/lseek, use size_t and off_t types, as mandated by
POSIX:
http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/unistd.h.html
Also, prototypes of unistd.h functions should not depend on
CONFIG_POSIX_FS, as (many) of them deal with generic I/O, not with
files in filesystem per se.

It so happened that previously CONFIG_PTHREAD_IPC served this role.
But pthreads and IPC is only parts of POSIX, orthogonal to other
services.
Move CONFIG_POSIX_FS, etc. out from CONFIG_PTHREAD_IPC.

Under GNU C, sizeof(void) = 1. This commit merely makes it explicit u8.
Pointer arithmetics over void types is:

Make if statement using pointers explicitly check whether the value is
NULL or not.
The C standard does not say that the null pointer is the same as the
pointer to memory address 0 and because of this is a good practice
always compare with the macro NULL.

Add a private variable `rt_clock_base` that can be used to determine a

When a mempool is created with a large number of maximum-size blocks,
the logic for initializing max_inline_level (i.e. when to union the
bitmask with the pointer and when to use the pointer directly) was
wrong. The default state was "zero", which implies that level 0
should be inlined, but that's wrong with >32 base blocks.
Additionally, the type was unsigned, making the "level zero is a
pointer" situation impossible to represent.

Consistently use
config FOO
bool/int/hex/string "Prompt text"
instead of
config FOO
bool/int/hex/string
prompt "Prompt text"
(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).
The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.
Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some
of the rarer variations had to be converted manually.
