[PATCH 2/3] Use %m instead of strerror() in syslog messages

[=?unknown-8bit?q?R=C3=A9mi?= Denis-Courmont]

[-- Attachment #1: Type: text/plain, Size: 6825 bytes --]

strerror() is not thread-safe, nor in the glibc implementation,
nor in the POSIX specification. In my experience, it will infrequently
crash when another thread uses locale data in any way, including
string formatting and such...

Since the Huawei driver uses thread, we might as well avoid strerror().

Hmm, yeah. I misread the code. That comment is wrong.

I applied this patch but broke it up into four:

- isimodem

So my question is why we're using g_printerr in the first place inside a
library.  Perhaps an approach similar to g_at_chat_set_debug is in order?

Since we do not use threads, do you still want this patch?  If you do,
can you please break this up into two patches, one for drivers/isimodem
and one for plugins?  We prefer patches to be split by directory.

You might also want to fix the style violation above, the opening brace
should be on the same line as the if statement.

I don't know. I guess I will wait for Aki's infamous rewritten gisi anyway.

Why do we initialize glib and dbus with thread support? If the plan is to 
smoothen the hypothetical use of threads in the future, then this patch should 
probably go in as well?

we do not initialize it with thread support, but in case a plugin
actually uses threads it could force it. This is common across BlueZ,
ConnMan and oFono and really just in case thing. In ConnMan we have this
case with the WiMAX plugin. For oFono we should hopefully never require
threading support.
