f877b82573 gresolver: add missing locking
This is sad, but GResolver has one member variable for historical
reasons, to implement the reload signal. Since it offers a global
singleton, we should make sure it's really safe to use from multiple
threads at once.

c2b5fe9f2d gresolver: remove unneeded call to res_init()
This call was needed once upon a time, when GResolver had subclasses
that presumably relied on this. Nowadays, we have only
GThreadedResolver, which does not need it. res_init() is dangerous
because it modifies global state, so let's get rid of it.

b08bd04abe gtask: Improve task names used internally within GLib
And improve them externally, where not otherwise set, by setting them
from the function name passed to `g_task_set_source_tag()`, if called by
third party code.

This should make profiling and debug output from GLib more useful.

ea99872e45 Always resolve localhost to loopback address
This always resolves "localhost" to a loopback address which
has security benefits such as preventing a malicious dns server
redirecting local connections and allows software to assume
it is a secure hostname.

This is being adopted by web browsers:

273c00f620 gio: ensure default va_marshaller is used
If c_marshaller is provided during g_signal_new() registration, the
automatic va_marshaller will not be set. If we leave the c_marshaller as
NULL in the simple cases, both a c_marshaller and va_marshaller will be
set for us.

This is particularly helpful when dealing with stack traces from Linux
perf, which often cannot unwind the stack beyond the ffi_call_unix64
stack-frame on x86_64.

18a33f72db introspection: use (nullable) or (optional) instead of (allow-none)
If we have an input parameter (or return value) we need to use (nullable).
However, if it is an (inout) or (out) parameter, (optional) is sufficient.

It looks like (nullable) could be used for everything according to the
Annotation documentation, but (optional) is more specific.

10bac98185 gresolver: Mark GResolver as an abstract class
It only works through its virtual methods, so while it could be
instantiated before (and this is technically an API break), any instance
of it would previously have crashed as soon as any of its methods were
called anyway.

If anybody has any problems with this ABI break, please make them known
during the 2.51 unstable development cycle and it can be reverted.

14b0c15abb gresolver: Document that GResolver lists are non-empty on success
The documentation previously wasn’t clear about whether the GResolver
methods could return an empty list and no error. On balance, this seems
like a bad idea, and GResolver should commit to always return a
non-empty list, or an error (which should be G_RESOLVER_ERROR_NOT_FOUND
if the list would otherwise be empty).

5575a3e9cb gio: don't accept nonstandard IPv4 "numbers-and-dots" addresses
In addition to the standard "192.168.1.1" format, there are numerous
legacy IPv4 address formats (such as "192.168.257",
"0xc0.0xa8.0x01.0x01", "0300.0250.0001.0001", "3232235777", and
"0xc0a80101"). However, none of these forms are ever used any more
except in phishing attempts. GLib wasn't supposed to be accepting
these addresses (neither g_hostname_is_ip_address() nor
g_inet_address_new_from_string() recognizes them), but getaddrinfo()
accepts them, and so the parts of gio that use getaddrinfo()
accidentally did accept those formats.

Fix GNetworkAddress and GResolver to reject these address formats.

c6c1166566 GNetworkAddress: drop cached addresses on resolver reload
If the resolver reloads (ie, if /etc/resolv.conf changes),
GNetworkAddress needs to re-resolve its addresses the next time it's
enumerated. Otherwise hosts that have different IP addresses inside
and outside a VPN won't work correctly if you hold on to a
GNetworkAddress for them for a long time.

b377e69685 Add gnetworking.h
Install a public "gnetworking.h" header that can be used to include
the relevant OS-dependent networking headers. This does not really
abstract away unix-vs-windows however; error codes, in particular,
are incompatible.

gnetworkingprivate.h now contains just a few internal URI-related
functions

Also add a g_networking_init() function to gnetworking.h, which can be
used to explicitly initialize OS-level networking, rather than having
that happen as a side-effect of registering GInetAddress.

deprecation warnings) by adding a "legacy" GAsyncResult method
to do it in those classes/methods where it had been traditionally
done.

(This applies only to wrapper methods; in cases where an _async
vmethod explicitly uses GSimpleAsyncResult, its corresponding _finish
vmethod still uses g_simple_async_result_propagate_error.)
