[rfa/doc] Do not use formal parameters named "current_gdbarch" in the docs

["Ulrich Weigand" <uweigand@de.ibm.com>]

Hello,

gdbint.texinfo contains a number of cases where the struct gdbarch *
formal parameter of a gdbarch callback function is shown with the name
"current_gdbarch".  This is somewhat confusing, as the sources never
do that (and for good reason, because it would shadow the current_gdbarch
global variable).

In addition, this causes some false positives when grepping the sources
for current_gdbarch instances that are to be eliminated.

The following patch renames those formal paramters to "gdbarch", as
is common usage in GDB source code.

OK to apply?

Bye,
Ulrich


ChangeLog:

	* gdbint.texinfo: Rename formal parameters to gdbarch function
	protoypes from "current_gdbarch" to "gdbarch".
