Chandler Carruth 2b3c00eec7 Revert r179012: "[msan] Intercept glob()." 
This was committed without tests and contains obvious bugs. That's not
acceptable. It broke address sanitizer for most programs using glob(3).

Evgeniy Stepanov b5ec3a2d55 [sanitizer] More accurate scanf parsing without GNU extensions. 
In __isoc99_*scanf we don't have to worry about GNUisms, and can parse
%a accurately.

could potentially happen, but did not.

Evgeniy Stepanov 87c43537df [sanitizer] Improve scanf interceptor 
This a rewrite of the scanf parser. The new implementation is pretty close to
the spec, with a few shortcuts taken here and there. It is conservative, i.e.
it gives up parsing if it does not understand some part of the format string,
or runs into an ambiguous % spec. It does not handle some rarely used parts of
the spec, like %n$ - for now.

I'm also moving parser call to after the original *scanf function completes,
so that we can find out the store size of %s directive by the use of strlen()
on the target buffer.
