The deamon should never stop respawning. Way to important!
Change upstart to respawn forever
This prevents two defunct sub processes hanging around.

Better systemd service file
Also use consistent heading.
Removed instructions for using -t flag Moved check_requirements function from main to mbpfan Moved daemonize and verbose globals from main to daemon Moved strings for program information from main to global.h Moved strings for coretemp and applesmc paths from main to mbpfan.c Updated Makefile Turned on verboseness for testing
Useful for monitoring intel_pstate effects.
Run with: clang-format -i src/* Closes #233.
The run directory has been moved from /var/run to /run in systemd, which results in the following warning at boot: ``` /usr/lib/systemd/system/mbpfan.service:10: PIDFile= references a path below legacy directory /var/run/, updating /var/run/mbpfan.pid → /run/mbpfan.pid; please update the unit file accordingly. ``` Additionally, the service occasionally fails to start if the service is started before coretemp devices have finished probing, which results in the following error. This patch fixes this issue. ``` systemd[1]: Started A fan manager daemon for MacBook Pro. mbpfan[350]: /usr/sbin/mbpfan needs coretemp support. Please either load it or build it into the kernel.

When building with clang-16, the following build error is raised.
clang -c -O2 -march=x86-64 -pipe -pipe -frecord-gcc-switches -fno-diagnostics-color -fmessage-length=0 -g -Wall -Wextra -Wno-unused-function -std=c99 -D_POSIX_C_SOURCE=200809L -D_XOPEN_SOURCE=500 src/util.c -osrc/util.o
src/util.c:13:9: error: call to undeclared function 'vsyslog'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
vsyslog(level, fmt, args);
^
src/util.c:13:9: note: did you mean 'syslog'?
/usr/include/syslog.h:62:6: note: 'syslog' declared here
void syslog (int, const char *, ...);
This is due to vsyslog being available when _GNU_SOURCE or _BSD_SOURCE
is defined [1]. This patch does that, thus fixing the error.
