9d70646fcf allow godoc to match on regular expressions. 
if the name contains a metacharacter, use regexp matching;
otherwise require strict equality.

now
	godoc flag '.*Var'

dc5cffbeb7 Use the mutex in exvar.Set since map access is not atomic. 
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.

3cc702ba60 Initial cut at an "exported variables" (exvar) package. 
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.
