Introduce "protection_bypass" privilege.
This privilege allows map protection bypassing for server operators
and world moderators.
Initially I had thought that bypassing protection mods would have been
something that could entirely be done inside mods and minetest_game,
but the concept of protection is defined in core, in the code of
core.is_protected().
I don't feel that it would be logical to introduce a protection
concept in core, but not some way around that for server operators
to maintain map parts that need fixing, de-griefing or cleanup.
Others had noticed the same problems, and proposed a patch to
minetest_game. That patch is fine by itself, but it fails to add
protection bypass functionality for digging normal nodes and placing
nodes.
So, instead, we indroduce the new priv "protection_bypass" in core,
and modify 'on_place_node' and 'node_dig' to allow bypassing node
protections if the player holds this priv.
This priv was tested with protector redo by tenplus1.
A followup patch to Minetest Game will include allowing special checks
for doors, trapdoors, chests in Minetest Game.
Protection mods will likely want to mimic the changes in their relevant
code sections.

Add consistent monotonic day counter - get_day_count()
I've written several experimental bits of code that revolve around the
need for a consistent calendar, but implementing one is extremely hard
in mods due to time changes and mods overriding core.get_timeofday(),
which will conflict.
The second part of the problem is that doing this from a mod requires
constant maintenance of a settings file.
An implementation in core is trivial, however, and solves all of
these problems at virtually no cost: No extra branches in server
steps, and a single branch when minetest.set_time_of_day(), which is
entirely reasonable.
We store the day_count value in env_meta.txt.
The use case is obvious: This change allows mods to create an actual
virtual calendar, or properly account for seasonal changes, etc..
We add a "/days" chatcommand that displays the current day count. No
permissions are needed. It can only retrieve the day count, not
modify it.

Update Android dependencies, -O3 optimization, remove old ARMv5 config
* Update OpenSSL (thanks @sapier, i use his patch!), Curl and SQLite3.
* Remove old arm config. Almost all phones that use ARMv5 have 1 core and 256-512 RAM, it's about 2-5 FPS.
* Do -O3 optimization for libs and remove -fexpensive-optimizations for Minetest (-O3 includes this! Read gcc docs).
* OpenSSL fix - thanks @sapier, again.

Fix a mistake in the world format documentation
Fixed a minor mistake that made it appear as if the inventory
is serialized multiple times - once per each variable. In fact
it is serialized once per each node.

Sheet Ore: Eliminate crash caused by PcgRandom range max < min
In the calculation of y_start,
when 'column height max' was large it caused
nmin.Y + max_height > nmax.Y - max_height
Now, in this situation y_start is set to the
midpoint between nmin.Y and nmax.Y
Limit y0 and y1 to between nmin.Y and nmax.Y,
otherwise index calculation, which has no checks for limits,
places them at unwanted locations in the voxelmanip

Reset block send timer when invoking setBlock(s)NotSent()
As stated in this forum thread [1], I noticed that there is a
2 second interval in which inventory changes are shown on the
client. @yyt16384 found the source of these 2 seconds:
m_nothing_to_send_pause_timer is set to 2.0 every time there
are no changes to make, but this timer is not reset when
SetBlockNotSent or setBlocksNotSent are invoked. So in worst
case, the changed block will be sent over 2 seconds too late.
With this change, changed inventories are updated almost
immediately, but it causes additional connection load.

Add Lua interface to HTTPFetchRequest
This allows mods to perform both asynchronous and synchronous HTTP
requests. Mods are only granted access to HTTP APIs if either mod
security is disabled or if they are whitelisted in any of the
the secure.http_mods and secure.trusted_mods settings.
Adds httpfetch_caller_alloc_secure to generate random, non-predictable
caller IDs so that lua mods cannot spy on each others HTTP queries.

Fix backface culling when connecting to new servers.
Introduce a new contentfeatures version (8). When clients
connect using v27 protocol version, they can assume that
the tiledef.backface_culling is trustable, but if clients
connect to servers providing contentfeatures version 7,
then the v27 clients know that backface culling settings
provided by the server in tiledefs are bogus for mesh,
plantlike, firelike or liquid drawtype nodes.
