It could return a NULL if the realloc fails. This handles the failure in
the same way as other failures in wchar_to_str, it exits immediately
with an error message.

Subject: [PATCH 21/24] ui: Add checks for prompt being NULL
Also removes a cast from const char* to char* when passing to readline
that doesn't appear to be necessary any longer.
Added asserts to make sure prompt isn't NULL after strdup and realloc
calls.

Subject: [PATCH 22/24] tests: Fix formatting and snprintf warnings in tests.
The assert message includes sector values, which are long long int, so
use the proper formatting of %lld.
The snprintf warning complained about trying to write 258 bytes so I
bumped the buffer size up to 259. The return value is already being
checked for truncation so this is just to keep the compiler happy
without having to suppress the warning.

Subject: [PATCH] parted: Fix ending sector location when using kibi IEC suffix
This fixes a bug when using KiB to specify the ending location of a
partition. It was not subtracting 1s like it does with the other units
because it was looking for a 'k' not a 'K'.
This also fixes a quirk of the suffix checking code, it would check for
matching case, but converting to the actual IEC value was case
insensitive. This now uses common functions for the matching so that
case doesn't matter.
It also adds tests to check for the fix.
The only change in behavior is that using KiB to specify the ending
location of a partition will now correctly create the end 1s lower than
the specified location like it does for MiB, GiB, etc.
