11caa6fcf2 heap: recognize 0x40000000 as an address terminating the backtrace 
On Xtensa, backtrace can not recover the two most significant bits of
the address, as the window call size is encoded in these bits.
Because of this, __builtin_return_address modifies these MSBs to
match those of the callee, "fixing" the address. An unfortunate side
effect is that the zero return address, which usually terminates the
backtrace, gets converted to 0x40000000. While there is a valid
instruction at this address, its occurrence in the backtrace is
highly unlikely: this is the first instruction of WindowOverflow4
vector, and IDF apps switch VECBASE to an IRAM location very early at
startup.

769bd4a4af linker: When using section type attributes, create unique sections 
* Prevents section type conflict errors if (say) const & non-const data
  is put into the same section (ie with DRAM_ATTR)

* Allows linker --gc-sections to remove unused custom sections
