This is the AVR port from Michael, release (merge) candidate 5.

The series can be found also in this repository:

https://github.com/AMarkovic/qemu-avr-merger-rc5

History:

Since v4:

- Alex tracing improvements (the only functional difference from v4)
- Moving code between patches, and sometimes between files
- Several new patches were extracted from more complex ones
- Improved commit messages
- Other minor improvements
- I added my 8 "R-b:"s that I explained in rc4, plus some more
- Series now has 0 errors and 0 warnings (checkpatch)

Since v3:

- Removed a patch on load_elf() modification, since it has been merged
- Removed references to CONFIG_USER_ONLY and provided a guard against
  building lunux user mode for AVR
- Removed all references to 'Atmel' (including file renames)
- Rebased the code (there was common interface change regarding 'props')
- Various corrections of commit messages
- A bit field for AVRFeatures is nor 64 bit long
- Other minor fixes

Since v2:

- First patch is split into six smaller logical units (net result
  remains the same)
- Patch "hw/core/loader: Let load_elf populate the processor-specific
  flags" was redone to reflect the original intent that was lost in
  transalation between multiple autors
- Patch "hw/avr: Add helper to load raw/ELF firmware binaries" was
  corrected only in one line to rectify type of "e_flags"
- Patch "target/avr: Add section about AVR into QEMU documentation"
- Spurious <message-Id:> elements were removed
- The series was rebased to the latest code

Since v1:

- Addressed Thomas comments
- Fixed a non-critical bug in ATmega (incorrect SRAM base address)
- Added ELF parsing requested by Aleksandar
- Dropped default machine (as with the ARM port)
