Subject: Add 'src' dir to global include path
X-Git-Tag: v2.13.0-rc1~147
X-Git-Url: http://git.liburcu.org/?p=lttng-ust.git;a=commitdiff_plain;h=74e79a0da99992c182da26abf45447722eaa400d

Add 'src' dir to global include path

The objective is to move internal headers from the global 'include'
directory to their respective private directories under 'src'.

Move the private generated 'config.h' to 'src/common/config.h', this way
it can be include with 'common/config.h' and reduce the risk of clashing
with a similarly named file.

This is part of an effort to standardize our autotools setup across
projects to simplify maintenance.
