2910aa77b2 [network] Error handling reform
`network.cpp` has several error paths which either:
- report "Unhandled host socket error=n" and return `SUCCESS`, or
- switch on a few possible errors, log them, and translate them to
  Errno; the same switch statement is copied and pasted in multiple
  places in the code

Convert these paths to use a helper function `GetAndLogLastError`, which
is roughly the equivalent of one of the switch statements, but:
- handling more cases (both ones that were already in `Errno`, and a few
  more I added), and
- using OS functions to convert the error to a string when logging, so
  it'll describe the error even if it's not one of the ones in the
  switch statement.
  - To handle this, refactor the logic in `GetLastErrorMsg` to expose a
    new function `NativeErrorToString` which takes the error number
    explicitly as an argument.  And improve the Windows version a bit.

Also, add a test which exercises two random error paths.

6b7320add4 core: Remove unnecessary enum casts in log calls
Follows the video core PR. fmt doesn't require casts for enum classes
anymore, so we can remove quite a few casts.

0791082b43 network, sockets: Replace POLL_IN, POLL_OUT, etc. constants with an enum class PollEvents
Actually, two enum classes, since for some reason there are two separate
yet identical `PollFD` types used in the codebase.  I get that one is
ABI-compatible with the Switch while the other is an abstract type used
for the host, but why not use `WSAPOLLFD` directly for the latter?

Anyway, why make this change?  Because on Apple platforms, `POLL_IN`,
`POLL_OUT`, etc. (with an underscore) are defined as macros in
<sys/signal.h>.  (This is inherited from FreeBSD.)  So defining
a variable with the same name causes a compile error.

I could just rename the variables, but while I was at it I thought I
might as well switch to an enum for stronger typing.

Also, change the type used for values copied directly to/from the
`events` and `revents` fields of the host *native*
`pollfd`/`WSASPOLLFD`, from `u32` to `short`, as `short` is the correct
canonical type on both Unix and Windows.

39c8d18feb core/CMakeLists: Make some warnings errors
Makes our error coverage a little more consistent across the board by
applying it to Linux side of things as well. This also makes it more
consistent with the warning settings in other libraries in the project.

This also updates httplib to 0.7.9, as there are several warning
cleanups made that allow us to enable several warnings as errors.

51817f6e59 core/network: Add network abstraction
This commit adds a network abstraction designed to implement bsd:s but
at the same time work as a generic abstraction to implement any
networking code we have to use from core.

This is implemented on top of BSD sockets on Unix systems and winsock on
Windows. The code is designed around winsocks having compatibility
definitions to support both BSD and Windows sockets.
