Wentong Wu 6922d93d8e lib/posix: correct the meaning of CONFIG_MAX_PTHREAD_COUNT
Current code implement CONFIG_MAX_PTHREAD_COUNT as the maximum number
of POSIX threads that can ever be created, rather than the maximum
number of active POSIX threads. Use pthread_state of struct posix_thread
to track the state of posix thread in posix_thread_pool so that we can
reuse the unused posix thread.

Fixes #15516.

Kumar Gala b730fa4ccb posix_lib: Disable support on native posix arch
For now we are disabling support for POSIX lib on native posix arch.  We
need to cleanup and support POSIX lib cleanly for hardware targets.
Once that is working properly we can look to support the feature on
native posix arch.

Paul Sokolovsky f484bbaa26 lib: posix: Implement generic file descriptor table
The table allows to wrap read/write (i.e. POSIX-compatible) semantics
of any I/O object in POSIX-compatible fd (file descriptor) handling.
Intended I/O objects include files, sockets, special devices, etc.

The table table itself consists of (underlying obj*, function table*)
pairs, where function table provides entries for read(), write, and
generalized ioctl(), where generalized ioctl handles all other
operations, up to and including closing of the underlying I/O object.

Fixes: #7405

Paul Sokolovsky 8dc69e09da lib: posix: Add top-level define for all POSIX APIs - CONFIG_POSIX_API
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.

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
of the rarer variations had to be converted manually.

Ulf Magnusson 0785b79ebe lib: kconfig: Remove redundant 'default n' properties
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.

Ramakrishna Pallala f603e603bb lib: posix: Move posix layer from 'kernel' to 'lib'
Move posix layer from 'kernel' to 'lib' folder as it is not
a core kernel feature.

Fixed posix header file dependencies as part of the move and
also removed NEWLIBC related macros from posix headers.
