Integrated the VBA-SDL-H2 code into the GDB function. 

This allows breakpoints, memory views and watches to be controlled from the GDB interface.  The VBA-SDL-H2 commands can be entered via the GDB monitor (type "help" into the monitor for a list of commands).  Made minor changes to the GDB interface so that the GDB port does not need to be entered every session.  A "Break on Load" option has been added allowing GDB to be connected before the ROM starts executing.

/*New code made for the new breakpoint system.
Each breakpoint is now marked by a halfword in an array on map,
breakpoint array. Each bit means one different type of breakpoint.
Bit Value
0 - write
1 - read
2 - ARM
3 - THUMB
4 - Always on Write
5 - Always on Read
6 - Always on ARM
7 - Always on THUMB
Each flag is independant, and can be used as such, as well as together.
You can define a break on access (0xf), break on IO (0x3), break on
execution(0xc) or any other combination you need. 0xf0 will always break on
any passage through the address
This structure is accompanied by two other structures for the accesses.
One of them is the Conditional structure. It's available for all types.
The breaking address header is placed at ConditionalBreak. The type_flags
indicate the type of break, in the format indicated above.
Then, it links to the several conditions needed for the break to take place.
Those conditions are then sequentially executed, and if all are true, the
break takes place.
They are composed of an address to test, a value to test against, the value's
type, the flag conditons to test and a link to the next condition to test if
that was true. Address and value are stored as Evaluatable expressions,
according to the already defined eval from expr.c
However, be reminded that sometimes registers and memory positions may contain
values that are not addresses at some times. If such is the case, the program
will show garbage results or crash.
The flags are bit-based
Bit Value
0 - equal
1 - greater
2 - lesser
3 - force Signed comparison
Bit Value
0,1 - addr is: 00 - byte, 01 - halfword, 10 - word, 11 - undefined, assume word
2 - addr_is_signed
3 - addr_is_array of values (not implemented yet)
4,5 - 00 is byte, 01 is halfword, 10 is word, 11 undefined
6 - val_is_signed
7 - val_is_array (also not implemented)
Usage:
Instructions that accept this kind of implementation will follow this pattern
if <EXP_addr> <addr_type><op><val_type> <EXP_val> [<;>OR<||>OR<&&> [repeat]
if indicates that the following there is a condition. no If counts as always break
<EXP_addr> is the first value expression, that unlike what the name implies, may be
anything.
<op> is one of the comparation Operands. Full list bellow
<EXP_val> is the value to compare to.
Following can be a ||(or), that adds a second, independant break condition, or
a &&(and), that specifies that the next condition is a conjoined requisite to the break.
EX: [0x03005000] == 0x77777777 && 0x50 == [0x03005000]
Would be impossible, but tested anyway, and make it never break due to this condition.
[0x03005000] == 0x77777777 || 0x50 == [0x03005000]
Would make it break when the contents of 0x03005000 were either 0x77777777 or 0x50
Ex: to implement stop only when r2 is 0xf, use
if r2 == 0xf
to implement stop when PC is above 0x08005000 and 0x03005000 is signed halfword 0x2500
if pc > 0x08005000 && 0x03005000 == +0x2500
