kexec-tools: Make xc_dlhandle static
This patch is a follow-on to commit 894bea93 "kexec-tools: Perform
run-time linking of libxenctrl.so". This patch addresses feedback
from Daniel Kiper.
This patch implements Daniel's suggestion to make the
xc_dlhandle variable static, insert missing 'extern'
qualifier for the new __xc() wrappers, and correct some
style issues.
