We are still limited by /proc/*/cmdline size (4Kb max on Linux!).

In __isoc99_*scanf we don't have to worry about GNUisms, and can parse
%a accurately.

Respect REAL(scanf) return value and don't report memory stores that
could potentially happen, but did not.

Handle %a in cases when it is unambiguous.
Handle %m.

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.

[msan] add strip_path_prefix flag; print error summary; don't crash while printing summary if debug info is missing. The tests will follow later once we establish the lit-like tests for msan.

Use 64-bit inodes in file operations. ASan is now built with -mmacosx-version-min=10.5, thus the default inode
size is 32 bits. However the supported client code is going to target 10.6 and higher, where 64-bit inodes will be used.

[asan] print a short one-line report summary after the full report. Currently, works only if symbolization happens in-process.
