This patchset changes libweston to consistently use struct timespec for time values.
struct timespec is the standard way to represent time on Linux and allows for an improved range and accuracy compared to the millisecond based uint32_t values currently used in throughout the codebase. This change provides to users of libweston timestamps with higher accuracy, and will also allow libweston to more easily support future wayland interfaces that may require such high-accuracy timestamps. Note that this patchset breaks the libweston ABI, so we will need to bump the ABI version at some point. Patches (1) and (2) add more functionality to the timespec utilities to support the new uses cases introduced in the commits that follow. Patches (3) to (12) gradually transition libweston to use struct timespec. To make the changes more reviewable, each patch deals with only a specific aspect of the codebase. In order to limit the scope of each commit, some commits include temporary time value conversions to accommodate existing internal APIs. These temporary conversions are later removed as the internal APIs are also changed to used struct timespec.
