Ben10do 951c9b66f4 Don't segfault on null bytes in REPTs and MACROs
Previously, the copyrept() and copymacro() functions would halt their
first loop (in which they determine the length of the block)
prematurely,  causing an underflow when setting len, eventually causing
memory issues.

Whilst this doesn’t solve the len underflow entirely (e.g. if the file
ends immediately without an ENDR/ENDM), it should help with this exact
scenario of null bytes (as #50).

Ben10do 0a66e14307 Fix division by zero crashes in instructions
Previously, rgbasm could crash with a floating point exception if an
instruction includes a division or modulo by 0. Fixes #49.

Ben10do 06f0472f81 Emit a single error when using BANK incorrectly
Previously, if BANK is used when defining a section that’s not ROMX,
WRMAX, SRAM or VRAM, a second error message would appear, e.g. “(null)
bank value $1 out of range $5d to $0”.

This would appear due to the usage of uninitialised variables. This
change ensures that the uninitialised variables are not accessed when
using an invalid section.

This also silences compiler warnings about usage of uninitialised
variables.

Ben10do defd4f589e Add noreturn attribute to fatalerror()
Should silence compiler warnings that expect fatalerror() to return.

Ben10do e86a70d2cb Fix the name of the GNUmakefile
GNU make actually looks for ‘GNUmakefile’, not ‘GNUMakefile’.

Consequently, GNU make would erroneously attempt to use the standard
makefile, instead of the GNU-specific one. This would cause an error
when attempting to import png.h, due to PNGFLAGS not being correctly
set.
