Section ranges are on one of the types of custom sections
types used in Linux. This provides a series of helpers for
defining them and using them. Most importantly this also
enables us to avoid modifying the linker script when we
add new section range.

It turns out a lot of custom sections are actually section ranges,
and these are typically spelled out in their architecture specific
asm/sections.h file -- we anable architectures to override what asm
is used for section ranges but start by defult trusting the asm-generic
version all around.

v3: new in this series, uses copyleft-next
