Targets build during the kernel phase did not have their dependencies
specified and thus they were not rebuilt after their dependencies have
changed, for example by changing options in menuconfig.

This works by having the build system look for nuttx/external/Kconfig
to determine whether this directory is present or not. nuttx/external
is gitignored in order to be added by the final user but not to be
commited into the repo. Tipically this will by a symbolic link, just like
apps/external.
Inside external/ a Makefile should be placed with the same structure
than any nuttx/ subdirectory (eg: nuttx/drivers/). The
nuttx/external/Kconfig will be sourced and any options defined there will
appear at the bottom of menuconfig (unless options are conditioned on
menus, in which case they will appear accordingly).
The purpose is to allow arch/board independent code, which for any
reason is not to be upstreamed (propietary, not relevant for mainline,
testing, etc), to be built into the OS during OS building stage. This
way the user does not need to fork the NuttX repo to do so. This feature
complements well with external apps and custom board support.
So call 'make EXTRAFLAGS=-Wno-cpp' could suppress the warnings with pre-processor
directive #warning in GCC.

This port was effort of a number of people, I rather arbitrarily gave authorship to Guiding Li because he has the largest number of fundamental quashed commits from the Xiamoi repository.
Squashed commit of the following:
Author: Xiang Xiao <xiaoxiang@pinecone.net>
include/nuttx/b2c.h and libx/libc/string: Add non-standard string functions to deal with cases where there are more than 8-bits in a type char.
Author: Gregory Nutt <gnutt@nuttx.org>
Fix several build issues/missing definitiona needed for OpenAMP build in drivers/.
Add OpenAMP code has been reviewed and ran through tools/nxstyle (with all reports accounted for).
Author: Xiang Xiao <xiaoxiang@xiaomi.com>
tools/: Fix the minor issue in Makefile
Author: Gregory Nutt <gnutt@nuttx.org>
drivers/rptun/rptun.c: Review for coding standard. Run against tools/nxstyle.
tools/LibTargets.mk: Fix some TABs that were turned into spaces by a copy-paste.
fs/hostfs: Add configure and build support for hostfs RPC.
drivers/timer: Add configure and build support for syslog RTC.
drivers/syslog: Add configure and build support for syslog RPC.
drivers/serial: Add configure and build support for serial RPC.
Kconfig, tools/*.mk. openamp/: Add basic OpenAMP build support.
drivers/rptun: Add configure and build support for OpenAMP tunnel drivers.
drivers/net: Update Make.defs and Kconfig for OpenSDA support.
Remove drivers/clk/clk-rpmsg.c drivers/power/rpmsg_regulator.c. These depend on upstreaming support for a new subsystem based on the clk/regulator is model from Linux. Removed because we want to separate the activities. We will just try to get the basic OpenAMP support in place for now.
Remove drivers/misc/misc_rpmsg.c and include/nuttx/misc/misc_rpmsg.h. These are specific to the Xiaomi application.

Provided changes add option (CONFIG_EXECFUNCS_GENERATE_SYSTEM_SYMTAB) to build complete list of available functions and syscalls automatically. The symbolic table is generated in form libsymtab.a which can be reused by application or directly pull in when "g_symtab" and "g_nsymbols" variables are requested by EXECFUNCS configuration.
I have tried to follow mechanisms for library compilation in different kernel protection modes but tested only flat no-MMU build. The basic assumption is that this library and libraries providing syscall stubs and C-library functions are available in user-space context and initial application (usually NSH) registers the symbol table through IOCTL. The table can be reused then by another applications in their address space as kernel allows. Simple for flat or protected mode, I am not sure if really support in MMU mode. It is highly probable that I have made some mistake, overlooked something, but functionality is optional (should not cause troubles in any mode if disabled) and main purpose is to lower memory overhead when more applications are loaded on memory constrained system which usually use direct kernel calling without protection or address space separation. If the table should be provided by kernel to applications then makefiles has to be adjusted.
Move boards to boards folder
* boards: rename configs folder to boards
This is the proposed layout after the change:
boards: - folder containing board folders
<board>: - name of each board
drivers: - extra drivers specific for platform
include: - header files for the boars
scripts: - extra scripts specific for platform
src: - board specific code
tools: - extra tools specific for platform
<config>: - board specific configuration(s)
Note:
<xxx> names are dependent on platform
This is a logical change to aim to the arch layout but this is a
huge change it should be done in several steps to lower the risk.

In the two pass build, the application logic is built during the first phase, pass 1. In that phase, the application may generate and install source files in the pass1/directory. The operating system is built during phase 2 of the build. At that time, those source files in the pass1/ directory will be built and incorporated into the kernel address space.
The primary purpose of the pass1/ directory is to such application-generated kernel symbol tables. For an example of the use of this feature, look at apps/examples/module/drivers/Makefile. Kernel symbol tables are needed to support kernel modules. Of course, addition board-specific logic in, say, configs/<board>/src would have to be included to make use of the application-installed symbol tables.
Squashed commit of the following:
libs/libxx: Fix some confusing in naming. If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
libs/: Fix paths in moved library directories.
libs: Brute force move of libc, libnx, and libxx to libs. Cannot yet build it in that configuration.
