Send a unique X-Request-ID header to allow tracing requests in apache and owncloud logs

[butonic]

owncloud/core#28144 has been merged. It will use the value of a X-Request-ID header as the request id in log files to allow linking events on the client to events in the apache and owncloud logs.

• generate a string to use as unique id.
  • 20-200 chars
  • only [a-zA-Z0-9-+/_=.:] allowed
• use it in the client log
• send it as X-Request-ID header on every request

Client log only works if Android app is built with debug option, for example the beta builds in Play Store ad F-Droid (available in ownBrander too).

I've just implemented this within the network library replacement branch, commit cd60d63

i'd use UUID notation (as in new iOS app) for each request (32 hexadecimal digits: 8 + 4 + 4 + 4 + 12). I think it is a bit cleaner than using any character and any length between 20 and 200.

For logs in debug, including the id + method is enough info from my pov to debug-track issues

I think it was UUID v4
