Signed-off-by: Igor Fedorenko <igor@ifedorenko.com>

Updated timeout test to account for changed exception generation in httpclient:4.3.x (cf. HTTPCLIENT-1362)

Fixed set(key, null, null) to return true if current mapping is null/non-existing

Fixed DefaultRepositoryCache.put() to remove mapping if value is null

Bug 448409 - Output being spammed with "Using mirror ..." messages when running Maven with -X option

Reduced debug logging for mirror selection to log a given repository pair only once per session

Stored server and proxy credentials in separate providers and used new DemuxCredentialsProvider to delegate to one of those providers depending on host in auth request

Fixed implementation to use case-insensitive matching for non-proxy hosts
