Instead of atoi, strtol is used. This allows detection of typical
problems like empty value of key and incorrectly entered numbers.

Quorum is broken in this patch.

this flag (0|1) can be configured via quorum.last_man_standing and when
enabled, it allows expected_votes to be dynamically recalculated.
Assuming an 8 nodes cluster, every node votes 1 (mandatory requirement for
this feature).
In the first event, 3 nodes are lost.
The remaining partition of 5 is barely quorate.
After a configurable timeout (quorum.last_man_standing_window, default 10sec)
the quorate partition is allow to recalculate expected_votes based on
the remaining nodes.
This operation will bring expected_votes to 5 and quorum to 3.
Repeating the above loop, in the next event, 2 more nodes are allowed to
die. etc. etc.

this flag (0|1) can be configured via quorum.auto_tie_breaker and when
enabled, support for perfect even split is on.
In case of a 50% of votes loss in one single transition, the partition
with the node that has the lowest node id will remain quorate.

this flag (0|1) can be configured via quorum.wait_for_all and changes
behavior when granting quorum for the first time.
Normal behavior (default / 0) grants quorum as soon as enough nodes
are available in a cluster.
Setting this value to 1 will grant quorum only after all cluster
memembers are part of the cluster at the same time.

Our preferred shared logging system is exported via the libqb library. As
a result, the corosync project no longer needs to export logsys.so and the
code can be directly included in the binary. The header file can also be
removed.

Corosync has problem with readdir_r if pathconf function fails.
Main problem is hidden in calling pathconf (internally calls statfs)
which may fail. After this fail, newly allocated memory for readdir_r
was smaller than expected and memory was overwritten by readdir_r.
Patch removes calling of pathconf and rather use NAME_MAX constant which
is always large enough for all file systems.
Also return value of malloc SHOULD be checked.

strstr_rs used strdup and didn't handle failure. This change removes
the use of strdup as well as the uses of strstr, since all callers
passed a string of length 1 as the second argument. This also changes
the prototype so that the 2nd parameter is a byte, not a string.

* util.c (strstr_rs): Rewrite/simplify.
