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.

The read/write implementations call directly into the console drivers
using the hook mechanism, causing faults if invoked from user mode.
Add system calls for read() and write() such that we do a privilege

The stdout console implementations for minimal libc call directly into
the various console drivers (depending on what specifc hooks are
registered) causing faults when invoked from user mode. This happens,
for example, when using printf() which eventually ends up calling
fputc().
The proper solution is to ensure privileges have been elevated before
the _stdout_hook is called. This was already done for printk().
puts() and fputs() have now been re-defined in terms of the
fputc() and fwrite() functions, which are now system calls.

The errno "variable" is required to be thread-specific.
It gets defined to a macro which dereferences a pointer
returned by a kernel function.
In user mode, we cannot simply read/write the thread struct.
We do not have thread-local storage mechanism, so for now
use the lowest address of the thread stack to store this
value, since this is guaranteed to be read/writable by
a user thread.
The downside of this approach is potential stack corruption
if the stack pointer goes down this far but does not exceed
the location, since a fault won't be generated in this case.

If we use newlib the isdigit (and other similar functions) return an

possible warning when -Wpointer-sign is enabled.

For some reason %F wasn't supported initially. Its simple enough to
handle the case difference in infinity and NaN handling to add support
for %F.
Signed-off-by: Kumar Gala <kumar.gala@linaro.org>
The C standard says that %f should use '[-]inf' or '[-]infinity' (which
style is implementation defined) for infinity handling and '[-]nan' for
NaN.
We where adding a '+' and had the wrong case for 'inf' and 'nan'.
Before -> After
+INF -> inf
-INF -> -inf
NaN -> nan

For %{e,E,g,G} conversion specifiers the C standard says the exponent

Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.
Also simplify the default on STDOUT_CONSOLE. Defaults can be arbitrary
expressions, not just fixed values.

The charmap table used by strncasecmp() not only used precious 256
bytes of ROM, it also had wrong mappings outside the ASCII range
(123..218).
Rewrite strncasecmp() to call tolower() instead; might be a tiny wee
little bit slower than the current version, but it's not used in any
performance-sensitive parts of the code to justify the waste.
This reduces the ROM footprint for the ws_echo_server sample by ~224
bytes.

The pthread mutex changes went in with an adaptation to build with the
new wait queue API, but they did it by using the old dlist hooks
directly through typecasting and union assignment. That... is sort of
the opposite of the intent to having the new API be abstracted. The
pthread code worked, but failed once wait queues (on x86) stopped
being dlists.
Simple fix once I saw the problem, anyway.
