Mr-DaveDev eef702b3d7 Fix builds on musl based systems 
* Fix pthread_setname_np detection

Commit 6617c6f2c8 replaced
AC_LINK_IFELSE with AC_COMPILE_IFELSE. This has broken the
pthread_setname_np detection as compilation will always succeed even if
pthread_setname_np is not available (if the function is not found, a
simple warning will be displayed in config.log).

The correct fix is to put back AC_LINK_IFELSE with -pthread in LIBS
otherwise compilation will fail on toolchain without pthread_setname_np.

* Check for pthread_getname_np

On some toolchains (like musl), pthread_setname_np is available but not
pthread_getname_np so add this check in configure.ac

* DIFFERENCES BETWEEN imgs.width, conf.width AND rotate_data.cap_width

* ===========================================================================
* Location Purpose
*
* conf The values in conf reflect width and height set in the
* configuration file. These can be set via http remote control,
* but they are not used internally by Motion, so it won't break
* anything. These values are transferred to imgs in vid_start.
*
* imgs The values in imgs are the actual output dimensions. Normally
* the output dimensions are the same as the capture dimensions,
* but for 90 or 270 degrees rotation, they are not. E.g., if
* you capture at 320x240, and rotate 90 degrees, the output
* dimensions are 240x320.
* These values are set from the conf values in vid_start, or
* from the first JPEG image in netcam_start. For 90 or 270
* degrees rotation, they are swapped in rotate_init.
*
* rotate_data The values in rotate_data are named cap_width and cap_height,
* and contain the capture dimensions. The difference between
* capture and output dimensions is explained above.
* These values are set in rotate_init.
