semaphore:sem_boostholderprio prevent overrun of pend_reprios

Approved-by: Gregory Nutt

  The second case rtcb->sched_priority <= htcb->sched_priority
  did not check if there is sufficient space in the pend_reprios
  array.

Partial Fix priority inheritance  CONFIG_SEM_PREALLOCHOLDERS=0

  sem_findholder would fail and code optimization coverd this up.

Move wireless IOCTLs from include/nuttx/net/ioctl to include/nuttx/wireless/wireless.h.  Add some linux compatible structures to use with the IOCTL commands.

If whence is SEEK_END, the file offset shall be set to the size of the file plus offset. Noted by eunb.song@samsung.com

Networking: Add registration support for integrated ieee80211 wireless drivers.  Rename CONFIG_IEEE802154 to CONFIG_WIRELESS_IEEE8021514 following the convention of including the location of the configuration variable as a part of its name.

Photon: add basic support for wlan chip

STM32; OTG host implementations of stm32_in_transfer() must obey the polling interval for the case of isochronous and itnerrupt endpoints.

STM32 OTG HS:  A little research reveals that only the F2 RCC initialization set the OTGHSULPIEN bit and Photon is the only F2 board configuration that uses OTG .  Therefore, we can simplify the conditional logic of the last PR.  Negative logic was used (#ifndef BOARD_DISABLE_USBOTG_HSULPI) to prevent bad settings in other configurations.  But give these facts, the preferred positive logic now makes more sense (#ifdef BOARD_ENABLE_USBOTG_HSULPI).

STM32: Review of last STM32 F2 PR.  Progate changes to STM32 F4 and F7 OTGHS.  Rename some configs/photon/src files.  Naming can be either photon_ or stm32_ but must be consistent.
