gallium/hud: Add support for block I/O, network I/O and lmsensor stats 

V8: Feedback based on peer review
    convert if block into a switch
    Constify some func args

V7: Increase precision when measuring lmsensors volts
    Flatten patch series.

V6: Feedback based on peer review
    Simplify sensor initialization (arg passing).
    Constify some func args

V5: Feedback based on peer review
    Convert sprintf to snprintf
    Convert char * to const char *
    int arg converted to bool
    Func changes to take a filename vs a larger struct.
    Omit the space between '*' and the param name.

V4: Merged with master as of 2016/9/27 6pm

V3: Flatten the entire patchset ready for the ML

V2: Additional seperate patches based on feedback
a) configure.ac: Add a comment related to libsensors

b) HUD: Disable Block/NIC I/O stats by default.
Implement configuration option --enable-gallium-extra-hud=yes
and enable both statistics when this option is enabled.

c) Configure.ac: Minor cleanup to user visible configuration settings

d) Configure.ac: HUD stats - build system improvements
Move the -lsensors out of a deeper Makefile, bring it into the configure.ac.
Also, rename a compiler directive to more closely follow the standard.

V1: Initial release to the ML
Three new features:
1. Disk/block I/O device read/write stats MB/ps.
2. Network Interface RX/TX transfer statistics as a percentage
   of the overall NIC speed.
3. lmsensor power, voltage and temperature sensors.

The lmsensor changes makes a dependency on libsensors so support
for the change is opt out by default.
