Subject: [PATCH v2 1/2] Export linux/syslog.h

Userspace programs (like util-linux' dmesg) still use magic numbers for
the klogctl function (glibc's interface to the syslog system call).
Exporting linux/syslog.h makes the more descriptive named constants
available as a single reference for these values.

Signed-off-by: Paul Bolle <pebolle@...cali.nl>

Changes in v2:
- dropped the "Syslog internals" comment;
- dropped Kees' Singed-off-by, since the patch has changed.
