28a1e40ebd core/lib/settings: Generalized Settings Manager to work on any platform
This commit moves the Settings Manager from the AVR codebase
into the Contiki core library. Any platform that implements
the Contiki EEPROM API can now use the Settings Manager's
key-value store for storing their persistent configuration info.

The Settings Manager is a EEPROM-based key-value store. Keys
are 16-bit integers and values may be up to 16,383 bytes long.
It is intended to be used to store configuration-related information,
like network settings, radio channels, etc.

 * Robust data format which requires no initialization.
 * Supports multiple values with the same key.
 * Data can be appended without erasing EEPROM.
 * Max size of settings data can be easily increased in the future,
   as long as it doesn't overlap with application data.

The format was inspired by the [OLPC manufacturing data format][].

Since the beginning of EEPROM often contains application-specific
information, the best place to store settings is at the end of EEPROM
(the "top"). Because we are starting at the end of EEPROM, it makes
sense to grow the list of key-value pairs downward, toward the start of
EEPROM.

Each key-value pair is stored in memory in the following format:

Order    | Size     | Name         | Description
--------:|---------:|--------------|-------------------------------
       0 |        2 | `key`        | 16-bit key
      -2 |        1 | `size_check` | One's-complement of next byte
      -3 |   1 or 2 | `size`       | The size of `value`, in bytes
-4 or -5 | variable | `value`      | Value associated with `key`

The end of the key-value pairs is denoted by the first invalid entry.
An invalid entry has any of the following attributes:

 * The `size_check` byte doesn't match the one's compliment of the
   `size` byte (or `size_low` byte).
 * The key has a value of 0x0000.

5afcbf6fff Makefiles: Allow setting UIP_CONF_IPV6=0 to work as expected.
Setting UIP_CONF_IPV6 to zero from the make build command line is
something that seems like it should ensure that IPv6 is disabled, but in
fact it actually *enables* IPv6. This seems counter intuitive, so this
patch changes the behavior of the makefiles to handle this case
properly.

e13dc1d5ee Provide a way to add additional TARGET search directories.
E.g. in a makefile do:

TARGETDIRS += ../targets

This will search for targets in ../targets as well as
$(CONTIKI)/platforms

A error will occur if more than one targets with the same name are
found.

7a228fea41 Replaced classic approach of generating dependency files via rule with generating them as side effect of generating object files. The issue with "No rule to make target ..." is solved as suggested in http://make.paulandlesley.org/autodep.html.
At least with gcc (and cc65) the dependency files are generated without an additional run of the C compiler. This is especially beneficial on Cygwin because of the fork() performance issue.

b21b874801 Having the C preprocessor macro CONTIKI_TARGET set to $(TARGET) turned out to be not that useful for conditionals. Therefore I switched to having the macro CONTIKI_TARGET_$(TARGET) set (to the default value of 1).
In order to allow for clean C code with the usual all-uppercase macro names $(TARGET) had to be converted to uppercase. Gnumake doesn't have a builtin string function for doing so, therefore sed is called. The Gnumake doc section 14.2 lists sed as one of the utilities a makefile can always presume to be available. However it states that only generally supported utility options should be used. So the GNU sed extension \U was intentionally avoided.
