environment features. Drop it from various places where it is not needed.

Move these functions to the new header file and rename set_default_env()
to env_set_default() so that it has a consistent env_ prefix.

As part of the effort to remove things from common.h, create a new header
for the gzip functions. Move the function declarations to it and add
missing documentation.

This implements a stack usage check in SPL.

Many boards start up SPL to run code + data from one common, rather small
SRAM. To implement a sophisticated SPL binary size limit on such boards,
the stack size (as well as malloc size and global data size) must be
subtracted from this SRAM size.

However, to do that properly, the stack size first needs to be known.

This patch adds a new Kconfig option:
- SPL_SYS_REPORT_STACK_F_USAGE: memset(0xaa) the whole area of the stack
  very early and check stack usage based on this constant later before the
  stack is switched to DRAM

Initializing the stack and checking it is implemented in weak functions,
in case a board does not use the stack as saved in gd->start_addr_sp.

Support load of the U-Boot image from raw SATA disk sector. This is
equivalent to load from MMC raw sector.

Use CONFIG_IS_ENABLED(WDT) to permit use of WDT in SPL without DM,
while the full U-Boot can use rich DM/DT WDT driver.
