FS: Remove inode_search_nofollow().  That logic is no handled with a new field in the input argument structure.

Soft links: Fix logic and remove kludge of last commit.  Rename inode_dereference() as inode_linktarget() and make global.

FS: Separate inode_search() and inode_free() from fs_inode.c and put in separate files.  Flesh out symbolic link logic in stat() and readdir().  There are still some issues with stat().

STM32F429-DISCO:  Move some board initialization logic that is not usuable because it lacks the configuration options to make it so

STM32F7 SDMMC: Make sure that all SDMMC configuration variables begin with STM32F7_; Eliminate CONFIG_SDMMC1/2_DMA altogether.  Does not appear to be used.

Timer logic: Add private function prototypes to eliminate a warning; Functions should not be inline because the may recurse.

STM32F103-Minimum:  Fix a compile error.  CONFIG_STM32_TICKLESS_ONESHOT_TIMER is only defined in TICKLESS mode.  Somebody has been hand editing .config files.

CONFIG_SDIO_DMA: Was been defined in several low-level architecute Kconfig files, but used at the highest levels in the code.  Both are bad and both are fixed with this commit

Add capabilities() method to SDIO interface.  Remove CONFIG_SDIO_WIDTH_D1_ONLY.  That should not be a global propertie, but rather a capability/limitation of single slot when there may be multiple slots.

Typos withim mtd/ with Macronix MX25L.  In NuttX/drivers/mtd/Make.defs letters X between M and 25 are missing.  Noted by Oleg Evseev.

Module names are not needed in libc/modlib when the module library is used only for shared library support.
