This replaces the verbose and error prone pattern of calling
str = malloc(strlen("some value is 12345678"));
sprintf(str, "some value is %d", val)
with
str = aprintf(some value is %d", val);
This is similar to the GNU function asprintf() but returns the pointer
instead of assigning it to the first parameter. It uses the existing
gpi_vsnprintf(fmt, va_list) function.

The code (at least in this part of the project) is effectively formated
using tabs with a tab-size of 8 as a means for indentation.
There have been a few places where spaces were introduced. Some obviously
with an indent size of 8 in mind, others with an indent size of 4.
This commit tries its best to make the use of tabs consistent again, at
least for indenting lines. The "intra line" indentation (white space after
the first non-white-space character) is still a bit of a mess.
