b7810ffdb3 Check for section overflows in rgbasm
When allocating a section, allocate only the max possible size for that
type (only applies to ROM0 and ROMX).

When finding an overflow, in any kind of section, output an error with
the location of the line of code that caused the overflow.

6e123ccc36 Optimize allocation of buffers for sections
Instead of allocating 0x4000 bytes for all sections and resize them as
needed, allocate 0x8000 bytes and don't let them to be resized. This is
the max possible size (ROM0 when ROMX sections aren't present).

Buffers are not needed for RAM sections, this patch changes the code so
that it only allocates buffers for ROM sections.

7993d3455d Update alignment error handling
Ensure (in rgbasm) that the alignment value is between 1-16. Replaces the previous “alignment must not be negative” check.

1ab93a194e Implement ALIGN keyword in rgbasm
The ALIGN keyword specifies the number of bits that should be zero at the start of a section. It works in a simliar fashion to BANK.

e4cbf773f6 Add alignment of sections to objects
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.

49809f6caf Fix segfault in createpatch() when symbol is an inexistant local label or bank
Fixed as follows: if the symbol doesn't exist, don't add it to the relocation
table. The functions calling createpatch will nevertheless increment PC
correctly.

Test case:

SECTION "CODE", CODE
glob:
        jp .loc

; from test/asm/banknoexist.asm:
SECTION "sec", ROM0
        db BANK(noexist)

a014537837 reran indent (whitespace changes)
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):

-cli0

-di0
-i8
-ip
-l79
