i2ptunnel:
- Better timeout handling when reading headers in HTTP server (improved fix for ticket #723)
  Enforce total header timeout with new readLine()
- Prep for returning specific HTTP errors to client on request timeout and header errors,
  instead of just closing socket... further work to be in i2p.i2p.zzz.test2 branch
Streaming:
- Fix read timeout on input stream - was waiting too long, often twice as long as timeout, or more
  Enforce total timeout even when notify()ed
- Fix read() returning 0 on read timeout instead of -1 (possible fix for ticket #335)
  This prevents passing partial headers to server on timeout
- Fix javadocs for read timeout to match current behavior
- Fix StandardSocket SoTimeout to account for differences with I2PSocket readTimeout
- log tweaks

    - This change prevents tools that use the stats-file (/tmp/hsperfdata) from working (like jstat)

better error message to client
javadocs

add javadocs to specify where we do and don't (ticket #1491)

escape and truncate URL on error page

with a Writer or getBytes("UTF-8") for efficiency and to
avoid encoding issues.
Store strings as strings, not bytes.
Catch IOEs to prevent cascading error pages.
Minor cleanups

display new error page in HTTP client (ticket #643)
