Fix constants and setting ports

[syphyr]

Fix Orbot constants and set default dns port to 9053 which is the same default as c-tor.

@meenbeese could you please review this?

One thing that's annoying here is that many translations actually have this hardcoded to port 5400, not just the default.

One way would just be to update them all?

For example:

~/orbot/app/src/main/res/values-az/strings.xml:
   87      <string name="pref_transport_dialog">TransProxy Port Konfiqurasiyası</string>
   88      <string name="pref_dnsport_title">Tor DNS Port</string>
   89:     <string name="pref_dnsport_summary">Torun təklif etdiyi Port DNS işləyir (standart: 5400, yaxud söndürmək üçün 0)</string>
   90      <string name="pref_dnsport_dialog">DNS Port Konfiqurasiyası</string>
   91      <string name="pref_torrc_title">Torrc Xüsusi Konfiqurasiya</string>

~/orbot/app/src/main/res/values-be/strings.xml:
   89      <string name="pref_transport_dialog">Налада порта празрыстага проксі</string>
   90      <string name="pref_dnsport_title">Порт DNS Tor</string>
   91:     <string name="pref_dnsport_summary">Порт, на якім Tor прапануе свой DNS (па змаўчанні: 5400, 0 - для адключэння)</string>
   92      <string name="pref_dnsport_dialog">Налада порта DNS</string>
   93      <string name="pref_torrc_title">Карыстальніцкія налады Torrc</string>

~/orbot/app/src/main/res/values-bg/strings.xml:
   87      <string name="pref_transport_dialog">Настройка на порта на прозрачен сървър за прокси</string>
   88      <string name="pref_dnsport_title">Порт за DNS на Тор</string>
   89:     <string name="pref_dnsport_summary">Порт, на който Тор предлага услуга за DNS (подразбиран: 5400 или 0 за изключване)</string>
   90      <string name="pref_dnsport_dialog">Настройка на порта за DNS</string>
   91      <string name="pref_torrc_title">Потребителски настройки на Torrc</string>

Thanks for mentioning that. I have fixed it by updating them all with find . -type f -name 'strings.xml' | xargs sed -i 's/5400/9053/g'

@meenbeese could you please review this?

Thanks but can you rebase this on #1216? Otherwise, I will have huge conflicts once this is merged.

Done

I feel like there is a reason I chose 5400 and/or didn't use 9053...

[syphyr]

Currently, the default setting for the dns port is set to auto. So, Orbot will start looking for ports starting at 5400. It also seems like 9053 is a better starting point since the chance of the higher port number being taken by something else would be less.
