Series tools: use xen-tools/libs.h for common definitions | expand

Commit Message

Jürgen Groß Feb. 27, 2023, 3:41 p.m. UTC
Defining min(), min_t(), max() and max_t() at other places than
xen-tools/common-macros.h isn't needed, as the definitions in said
header can be used instead.

Same applies to BUILD_BUG_ON() in hvmloader.
