Core GDB

[BaranovMykola]

Create class to work with GDB. This class have to provide basics functionality to work with most of GDB functionality.

Class must have following:

• Open some project (set target exec, file, etc.)
• Write commands to GDB and receive respond
• Catch errors from GDB
• Start target program, step in\out\over
• Parse all local variables
• Set breakpoints
• Give type/content of given variable
• Set/Delete breakpoint
• Give list of all breakpoints
• Terminate executing target program
• Terminate executing GDB and target program

It's very convenient to use some extra classes: Breakpoint and Variable.
Breakpoint must contains type, line, function and enabled properties.

Variable must contains name, type and content. Also, Variable class must provides some functionality to parse nested structs.
