imxrt:Clock config fixes and board.h sets sources and divisors
* imxrt:clockconfig bug fix & Board config set clocks
Fixed logic that was not clearing bits as ~ was
mising in &= mask operations.
Use valuse from the board.h file so set the Mux that
selects the clock sources.
Use board defined PODF values to select clock.
Only configure USDHC2 clocks when board defines clocks.
* imxrt1050-evk:Board setting used to set LSPI and USDHC Clocks

1. Move exepath_*() related code to libc/misc
1. Rename exepath_ to envpath_
2. Rename BINFMT_EXEPATH to LIB_ENVPATH
libs/libc/modlib: Add pre module library symbol table support
tools/configure.c: Add missing '\n' in printf statement
tools/configure.c: Add missed -g option to getopt() string
tools/configure.c and tools/configure.sh: Fix Windows native pre-build kconfig-conf incompability. Looks like prebuilt Windows native kconfig-conf interprets "..\apps" as "..apps" (possibly '\a' as escape-sequence) so expand winnative path to double-backslashed variant "..\\apps".
tools/mkdeps.c: Fix '\0' missing in MinGW. Implicit bug. There are 2 cases.
1. Under Linux. The code works as planned: '\n' is always replaced with '\0' due to sprintf fills n-1 bytes and reaches buffer length limit.
2. Under Windows/MinGW. There is memory corruption. Seems like it`s a bug inside MinGW/snprintf. Snprintf fills consecutively "oldbase",' ',"str",'\n', but does not inserts trailing '\0' instead of '\n'. And when next append() occurs, strlen() returns garbage-appended "oldbase".
So the fix just removes '\n' and reserves space for '\0'.
tools/link.bat: Fix .fakelink creation
configs/Makefile and tools/Config.mk: Move single file copy to the new function COPYFILE. This fixes the Windows native build case when there is no cp or cp does not recognize Windows paths.

* Clocks were wrongly configured - way too fast because there is no primary divider on LPC4330
This is fixed by means of changing the definitions in the board.h file. I've edited the one for the lpc4330-xplorer board because I'm actually working with Versiboard and don't want to contribute that config just yet while I've still got the drains up on it.
* The LPC43_SDMMC_DELAY register was not being set
I suspect, in the 'real world', it's possible to get away without setting this, but I've added a register definition, default value and register access macros into arch/arm/src/lpc43xx/chip/lpc43_scu.h and then used them in arch/arm/src/lpc43xx/lpc43_sdmmc.c.
* The LPC43_SDMMC_BLKSIZ and LPC43_SDMMC_BYTECNT registers had the wrong values.
The management have already implemented a rather nice block level interface for the stm32 so I've just re-used that to write to these registers as required. I'm slightly nervous that accessing the configuration registers (SCR being the prime example) which has a much smaller block size may not be being done in the right way but it does seem to work correctly, so let's assume it's all OK until someone tells me otherwise.
These fixes have been tested with DMA-based read/write on a LPC4330. Speed via nsh is pretty low but I'm assuming that's just a buffering/implementation issue for now.

libs/libc/stdio/lib_libvsprintf.c: Resolves the integer field width problem if Issue 35 for the cases of long and long long integer types.
libs/libc/stdio/lib_libvsprintf.c: Resolves the integer field width problem if Issue 35 for the case of integer types.
libs/libc/stdio: Remove CONFIG_NOPRINTF_FIELDWIDTH. That option does, indeed, make the printf family of functions much smaller. But it also adds a lot of complexity and makes the functions non-standard. Removing this might break some of the tinier platforms but it is the best thing to do for long term maintanance for for OpenGroup.org compliance.
Squashed commit of the following:
fs/spiffs: Fix last compilation issue. Now compiles without error. It is still not quite ready for testing as there is additional code review that must be be performed. It is now marked as EXPERIMENTAL so that it can be brought onto the master branch with little risk.
fs/spiffs: Remove some dead code.
fs/spiffs: Weak start of analysis of spiffs_nucleus.c. Renamed to spiffs_core.c
fs/spiffs: Rename spiffs_nucleus.c to spiffs_core.c
fs/spiffs: Remove spiffs_config.h. All configuration settings are now available in the SPIFFS Kconfig options.
fs/spiffs: Finished review, update, and repartitioning of spiffs_check.c. Added spiffs_check.h.
fs/spiffs: Finished review, update, and repartitioning of spiffs_cache.c. Added spiffs_cache.h.
fs/spiffs: Clean up some defines used in debug output statements.
fs/spiffs: Finished review, update, and repartitioning of spiffs_gc.c. Added spiffs_gc.h.
fs/spiffs: Now that VFS interface is completed, I have begun the long march of repartitioning the remaining functionality, reviewing logic, identifying dead code, and cleaning up loose ends.
fs/spiffs: Initial integration of MTD interface, replacing the SPIFFS native flash interface. Lots of open issues such as the use of pages vs. blocks vs. erase blocks and units of addresses, offsets, and lengths that are passed in function calls. Remove SPIFFS_USE_MAGIC support. That option (which default to OFF anyway), wrote a magic value at the beginning of every sector and support verifiable identification of the file system. It was not being and used and removing it makes life simpler.
fs/spiffs: Remove semaphore lock on the file object structure. Ultimately, the file access must modify the volume and access the volume structue which also has a exclusivity lock. So use of the volume lock alone should be sufficient.
Integrated the SPIFFS rename logic into the NuttX VFS. Removed non-standard application calls or convert them to IOCTL commands. These were converted to IOCTL commands: (1) integrity check, (2) garbage collection, and (3) format flash. These were removed: (1) Integrity check callback. These provided a lot of good information about the state of the file system, but such callbacks are not compatible with a POSIX compliant file system. (2) Index maps. The index maps were a performance improvement feature. The user could provide the memory and request that a region of a a file use that memory for improved lookup performance when accessing parts of the file. The fallback is the less performance lookup by traversing the FLASH memory. (3) Removed the quick garbage collection interface (the code is still used internally). Only the full garbage collection is available to the user application via IOCTL.
configs/sim/spiffs: A simulator configuration to use for testing SPIFFS.
fs/spiffs: Integrate SPIFFS logic into NuttX VFS bind() and unbind() methods.
fs/mount/fs_mount.c: Add SPIFFS to the list of drivers that require MTD vs block drivers.
fs/spiffs: Trivial changes, mostly from analysis of how to integrate the rename() VFS method.
fs/spiffs: Connect NuttX VFS unlink method to the SPIFFS_remove() function. Lots of name-changing.
fs/spiffs: Remove non-standard errno support. Remove bogus SPIFFS_LOCK() and SPIFFS_UNLOCK() macros.
fs/spiffs: Add NuttX VFS implementation for statfs() method. Clean up some of the accumulating compilation problems.
fs/spiffs: Add stat(), truncate() methods. Dummy out unsupport mkdir() and rmdir() methods.
fs/spiffs: Replace some of the custom error numbers with standard error numbers.
fs/spiffs: Hooks read(), write(), fstat(), ioctl(), opendir(), closedir(), rewindif(), and readdir() into the NuttX VFS.
fs/spiffs: Beginning the organization to work with the NuttX VFS. Lots of things are get broken!
fs/spiffs: Add spiffs.c which will be the interface between SPIFFS and NuttX. No very close at present, however.
fs/spiffs: Clean up some compile problems introduced by coding standard changes.
fs/spiffs: A little closer to NuttX coding standard.
fs/spiffs: Ran tools/indent.sh against all files. Closer to NuttX coding standard, but needs a lot more effort to be fully compliant.
fs/spiffs: This commit brings in version 0.3.7 of Peter Anderson's SPIFFS. The initial commit includes the core FS files (with some definitions destributed to their correct header files) and hooks into the build system.
