[OE-core] [PATCH 0/1] sanity.bbclass: check for validity of TMPDIR

From: Chen Qi <Qi.Chen at windriver.com>

This patch checks the validity of TMPDIR.

The TMPDIR must match the following regexp.
^/[a-zA-Z0-9\-_/.~]+$

Detailed tests about why I came up with this regexp are displayed at the end of this cover letter.

A major reason for why TMPDIR cannot support many special chars such as @ and # is that these
special chars are used by the sed command as its field separator in our recipes.

And here are things I want to make sure of.
1. For now, TMPDIR must be an absolute path. So do we need to make it support relative path?
2. I included the tilde (~) into the valid char set because `bitbake world' succeeded. But
   it's still possible the the tilde (~) will serve as the field separator in sed. So is it
   OK that I include it into the valid char set?


**********************  TESTING RECORDS  ****************************************
Test Case 1: use `bitbake minimal' on paths containing special chars
Here's the output.
