Paul Sokolovsky 52aa8061c0 libc: newlib: libc-hooks: Consistently use const void* as arg to write
write() function is not supposed to change buffer passed to it, so
propagate const pointer param to all write-like functions used/defined

Paul Sokolovsky c80f61a1a7 libc: minimal: Add dummy sys/stat.h [REVERTME]
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.

Paul Sokolovsky 8e1d78c357 libc: minimal: Make fcntl.h be at top level, not sys/fcntl.h
Placing it at sys/fcntl.h was due to mimicking internal newlib's

Paul Sokolovsky 7f9127578b include: posix: unistd: Fix prototypes and dependency
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.

Andy Ross 71ca65306c mempool: Fix bit pointer state for N_MAX > 31
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.

Ulf Magnusson 8cf8db3a73 Kconfig: Use a short, consistent style for prompts
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
