report-error.bbclass: new class to save build information when errors occur

Class is used to save data about errors after every task that failed.
Errors saved as json files in ERROR_REPORT_DIR (defaults to tmp/log/error-report).
To use this class one has to add INHERIT += "report-error" to local.conf.

scripts/send-error-report is a simple script that sends the json file
to a HTTP server that collects data (git://git.yoctoproject.org/error-report-web
is a Django web interface that can be used to receive and visualize
the error reports). The script will give you an URL where you can
find your report.
