Test the interaction between GDBHISTSIZE and .gdbinit 

The value inside the GDBHISTSIZE environment variable, only if valid,
should override setting the history size through one's .gdbinit file.

	* gdb.base/gdbinit-history.exp: Test the interaction between
	setting GDBHISTSIZE and setting the history size via .gdbinit.
