if the name contains a metacharacter, use regexp matching;
otherwise require strict equality.

now
	godoc flag '.*Var'
can give you all the FooVar functions.

Imagine your var has a value of zero. If you have a goroutine calling Set(5),
and another calling Increment(+1), then you only want one of these outcomes:
  - Set completes first, and then Increment occurs => 6
  - Increment completes first, and then Set occurs => 5

However, you could get a sequence:
  - read (for Increment) 0
  - set (for Set) 5
  - write (for Increment) 1
This results in a value of 1, which is undesirable.

Kudos to dnadasi for catching this.

This handles integer-valued vars in a singleton struct, and exports functions
for incrementing, setting and getting those vars, as well as rendering all the
vars in a standard format.

Demonstrate the use of the exvar package in the http/triv server.

this allows gotest to find the locally built package when doing
	make
	gotest
without this option, one would have to say
	make install
	gotest
which kinda defeats the purpose

based on discussions with rsc.
