Implement waiting algorithm for GEOIP_CHECK_CACHE,
so stat is called on every lookup.

*** ifndef WIN32 on netdb.h ? ***
In GeoIPCity.c you don't "#ifndef WIN32" the netdb.h include,
but in GeoIP.c you do.  Which one is right?

*** Warnings in GeoIP-1.2.1 before I made changes ***
GeoIPUpdate.c:73: warning: implicit declaration of function `_setup_dbfilename'
    I suggest a GeoIP_private.h file to include prototypes for
    _setup_dbfilename and other private functions also used by GeoIPCity.c

*** Drop the GeoIP_*_by_addr API calls ***
And now that I think of it, why do you need a seperate
GeoIP_region_by_addr and GeoIP_region_by_name since
the later does the work of the former just as efficently.
For backward compatibility you could #define GeoIP_region_by_addr
to GeoIP_region_by_name




Performance improvements suggested by Jason Linhart
1. cluster nodes to improve disk performance when using GEOIP_STANDARD
2. evaluate preformance of replacing binary tree with nodes containing 4 children

Write function to list countries, sorted by name.  Chris Gibbs contributed this which could be
used:

 int GeoIP_country_sorted_index[246] = {
  0, 5, 8, 61, 14, 3, 11, 7, 12, 6, 13, 9, 17, 1, 16, 15, 18, 32, 25, 21,

Proxy Authorization needs to decode reserved/unsafe characters
which may be encoded in the proxy credentials before
base64-encoding the Proxy-Authorization data.
