In some implementations of libc the function fread has the attribute
`warn_unused_result`, that is treated as an error by the compiler as
specified in the flags passed to it.

If the folder where the code is compiled is a valid git repository, the
version string is generated with `git describe`. If it isn't a valid
repository, a string included in the source code is used instead. This
one must be updated regularly as the toolchain is developed.

Previously, if the user wanted to modify CFLAGS, it was necessary to add
the options used in the Makefile as well, which doesn't make sense.
This patch splits CFLAGS into CFLAGS and the previously removed
REALCFLAGS so that the user can modify the arguments passed to the
compiler without having to worry about things like passing the list of
include directories.

Some commands, such as `DS`, `BANK[n]`, etc, don't allow the use of
negative constants, but there wasn't any check to prohibit the code from
trying to do so.
This patch adds the `uconst` type to the parser to use when a constant
is expected, but it mustn't be negative.

There are two ways in which the assembly process can fail:
1. If there is a really big problem that compromises the whole process,
the assembler has to stop right there and generate an error message.
This happens with unterminated REPT loops, macros, etc.
2. If the problem isn't that big and the process can still continue,
even though the final result is invalid, the assembler can try to
continue and warn the user about all errors it finds in the code.
This patch clarifies the use of each function and replaces the function
used in two places by the correct one.

This is hard to detect in MACROs, as there are legitimate uses for
MACROs that call themselves recursively.
For an EQUS, the problem is that its value may be modified at different
points in the source code, so the only way to detect a possible problem
is by doing an analysis at each usage of the EQUS.
Also, since an EQUS may expand to the name of a MACRO and a MACRO can
use an EQUS, it becomes even harder to check all possible problems that
come out of it. It's better to let this task to the programmer.

The max size of some section types depends on the flags passed to
rgblink. Instead of doing in rgbasm some checks (for the sections with
fixed size) and others in rgblink, all checks are now done in rgblink.

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.

When including a linkerscript from a parent one, the lexer didn't
include a newline character because the INCLUDE command was handled
before reaching the newline. This behaviour is needed to parse the last
line of a linkerscript correctly (it doesn't have a newline character).
However, this meant that when the included file was being parsed, the
first line was considered a continuation of the last line of the parent
script (the INCLUDE command), which means that the first line of an
included linkerscript could only contain a comment (or nothing at all).
This patch adds a newline character to the buffer used by the lexer so
that the parser will receive a newline and it will handle the first line
of the included file as expected.

`LD HL,n16` and `LD SP,n16` are handled in a different rule as
`LD r16,n16`, but they are also part of that rule.
This patch converts the `LD r16,n16` rule into two rules, one for doing
`LD BC,n16` and other one for `LD DE,n16`.
