a566a51c09 Use linker scripts rather than libcirom/objcopy tricks to arrange 
IRAM/IROM sections.

esp-open-rtos compiled code: .text goes into irom by default, symbols
explicitly marked with IRAM attribute go into iram.

SDK code: .text goes into iram by default, symbols marked with
ICACHE_FLASH_ATTR go into irom.

libgcc functions also go into iram by default.

f34e229bbc Allow specifying list of files in Makefiles as alternative to dirs 
Also allow xx_EXTRA_SRC_FILES
Let target component use name TARGET so TARGET_EXTRA_SRC_FILES, TARGET_SRC_DIR, etc.

0dbb6d31a5 Add IRAM attribute for IRAM loaded symbols, add to common FreeRTOS functions 
Closes #7.

It'd be nice to change the linker script so .text is always linked to
IROM instead of needing to objcopy each compiled file. The sticking
point for this is libgcc & libhal, which have symbols in .text that need
to be loaded to IRAM.

81afe58334 Change symbol extraction to use objdump not nm 
nm outputs warnings to stderr so hard to clean output.

Also now picks up global variables, like NMIIrqOn.

e743d03a78 Preprocess all binary SDK symbols to add an sdk_ prefix 
* This fixes the problem of axTLS symbols hmac_md5/hmac_sha1 having same
  name as symbols in libwpa (which have incompatible signatures)

* Also allows for easier identification and piece-by-piece removal of
  binary functions.

* Some libc symbols are not renamed, list is in lib/symbols_norename.txt
