To make the behaviour of the linkerscript consistent, every section read
from an object file must have an unique name. This is needed as the
linkerscript uses the name of sections to place them and it expects
every section to have a different name.
This doesn't break compatibility with the old behaviour that allowed to
continue sections if they had the same name, bank number and starting
address. That's still allowed because `rgbasm` outputs a single section
if this functionality is used, it is transparent to `rgblink`.

Aligned sections can now be created with out_NewAlignedSection(). This information is stored in created object files, and read by the linker.
The names of each section are also included in the object file, enabling potential improvements to error messages in the future.
Instead of reading into a pre-sized buffer, this function now uses malloc to create a buffer, and resizes it if necessary.
This reduces the risk of memory issues if a long string (< 255 chars) was encountered.
fatalerror() prints a given string to stdout and exits(5). It
cannot format text, so there was a string temptext used with
sprintf() to format text and pass it to fatalerror().
errx() can format text, and it prints to stderr.
As a bonus, this fixes the linking warnings from use of sprintf().
Merging lai's source with this one is very irritating because
they have different indentation styles. I couldn't find what profile
vegard used for his version, so I used these flags (which should bring
the source close to KNF):
-bap
-br
-ce
-ci4
-cli0
-d0
-di0
-i8
-ip
-l79
-nbc
-ncdb
