Allow for statements with the following syntax:
regex ?= value (set)
regex ?+= value (append)
regex ?<= value (prepend)
These operations are performed only for keys that match regex.
The whole key name must match the expression, so if regex is a regular string,
only the key whose name equals this string is modified.
This is useful for modifying all parameters of a certain type regardless of the
objects they apply to. For example, the following parameters specify the cdrom
filenames for different objects: cdrom_vm1, cdrom_vm2, cdrom. It is now
possible to modify all of them with a statement such
cdrom.* ?<= shared_
which would prepend the string 'shared_' to all cdrom filenames.
