9400cf2cd1 sched/group: On task creation, do not clone uninitialized descriptors.
Sockets are created in two steps:

1. The socket is allocated, then
2. The socket is initialized.

In SMP mode, there is a possibility that a pthread executing one CPU may create a new task while a pthread on another CPU has allocated the socket but not yet initialized it.  This commit updates the socket clone test to assure that the socket is both allocated and initailized.

Without the change, it is possible that uninitialized sockets could be cloned, leading to errors later in the newly started task.

57e8f0451a cxd56: add initial Nuttx audio driver
Adds an initial Nuttx audio driver supporting the Spresense CXD56.
Being a work in progress the driver has a number of limitations:
- Audio playback only, no recording yet.
- Only 16 bit stereo playback is supported.
- In practice only 48kHz playback is supported due to missing SRC.
- Configure driver in "Device Drivers --> Audio Device Support".

67ec3d7926 Remove CONFIG_CAN_PASS_STRUCT
This commit resolves issue #620:

Remove CONFIG_CAN_PASS_STRUCTS #620

The configuration option CONFIG_CAN_PASS_STRUCTS was added many years ago to support an old version of the SDCC compiler. That compiler is currently used only with the Z80 and Z180 targets. The limitation of that old compiler was that it could not pass structures or unions as either inputs or outputs. For example:

    #ifdef CONFIG_CAN_PASS_STRUCTS
    struct mallinfo mallinfo(void);
    #else
    int      mallinfo(FAR struct mallinfo *info);
    #endif

And even leads to violation of a few POSIX interfaces like:

    #ifdef CONFIG_CAN_PASS_STRUCTS
    int  sigqueue(int pid, int signo, union sigval value);
    #else
    int  sigqueue(int pid, int signo, FAR void *sival_ptr);
    #endif

This breaks the 1st INVIOLABLES rule:

Strict POSIX compliance
-----------------------

  o Strict conformance to the portable standard OS interface as defined at
    OpenGroup.org.
  o A deeply embedded system requires some special support.  Special
    support must be minimized.
  o The portable interface must never be compromised only for the sake of
    expediency.
  o Expediency or even improved performance are not justifications for
   violation of the strict POSIX interface

Also, it appears that the current SDCC compilers have resolve this issue and so, perhaps, this is no longer a problem: z88dk/z88dk#1132

NOTE:  This commit cannot pass the PR checks because it depends on matching changes to the apps/ directory.

3b53cd1e57 include/nuttx: Fix improper use of inline
I finally figured out why the ez80 code has gotten so big.  It is because people have been put putting big inline functions in header files.  That is a violation of the coding standard, since only c89 compatibility is required in all common code. But we have been tolerating inline function it because include/nuttx/compiler.h defines 'inline' to be nothing for C89 compilers.

As a result, static inline functions declared within a C file not so bad; the inline qualifier is ignored, if not supported, but otherwise all is well.

But it is catastrophic in header files.  Those static inline functions are included as static functions and implemented in EVERY file that includes those header files, even if the functions are never called.  That makes the code base huge!So there is another PR coming to fix some of the worst offenders.

This commit fixes two of the worst offenders I have encountered so far:  include/nuttx/sempahore.h and cache.h.  But there may be a few other changes needed.  Under include/nuttx there are still inline functions thread.h, inclue/nuttx/list.h, mutex.h, tree.h, and include/nuttx/crypto/blake2s.h with no protection for compilers that do not handler the inline qualifier.  Otherwise we are clean.

With the changes to these two header files, the size of the z20x build is reduced by about 40%.  And incredible size savings.

51a2171c71 ramlog: Remove g_ramlog_syslog_channel since it's same as g_default_channel

dcaaf2d912 ramlog: Remove all ramlog_consoleinit related code
Because we can get the same function by CONSOLE_SYSLOG/syslog_console_init.
BTW, it isn't a good choice to use g_ramlogfops as /dev/console since nsh
will read back what it send out which will surprise most people.

e7d9260014 arch: Customize the typedef of size_t instead of intptr_t
To ensure size_t same as toolchain definition in the first place and rename CXX_NEWLONG to ARCH_SIZET_LONG.  The change also check whether __SIZE_TYPE__ exist before CONFIG_ARCH_SIZET_LONG so our definition can align with toolchain(gcc/clang) definition automatically.

3c0b49448a Network Loopback Driver: A configuration option to control packet size.
Historically, the loopback driver used the largest packet size of all enabled link layer protocols.  This permitted packets to be forward via the loopbak device with no major loss of performance.  However, in experimenting with configurations where no other link layer protocols were enabled, this means the loopback packet size was set to the smallest possible size, to the SLIP minimum of 296 bytes.  This resulted in terrible loopback performance.

    This commit adds an option to increase the loopback packet size with the option CONFIG_NET_LOOPBACK_PACKETSIZE.

    The loopback driver packet buffer should be quite large.  The larger the loopback packet buffer, the better will be TCP performance of the loopback transfers.  The Linux loopback device historically used packet buffers of size 16Kb, but that was increased in recent Linux versions to 64Kb.  Those sizes may be excessive for resource constrained MCUs, however.

    The network still enforces the lower limit that is the maximum packet size of all enabled link layer protocols.  But this new option permits the loopback packet size to be increased from that.

    * net/Kconfig:  Adds CONFIG_NET_LOOPBACK_PKTSIZE option
    * include/nuttx/net/netconfig.h:  Assures that the packet size that is used is at least as large as the largest packet size of other link layer protocols.
    * drivers/net/loopback.c:  Use that larger packet size.
    * boards/sim/sim/sim/configs/tcploop/defconfig:  Set the loopback packet size to 1500
