We shouldn't allow mutex lock/unlock to silently do nothing if NULL is
passed, as that is very likely a bug. Beyond that the Windows version
doesn't do this, so it's inconsistent as well.
This moves a lot of the preprocessor flags for what compiler/platform
we're using into a libqb-common.h header inside the libqb/include
folder. This gets included at the top of every libqb .cpp file, and is
intended to be fairly small, providing only necessary things like
_WIN32_WINNT (which needs to be defined before including <windows.h> or
friends).
The Buffer API implements an append-only buffer, where you can write to
the end or read from the beginning. Data that is read is discarded from
the buffer, and you can query the buffer to get the current amount of
data inside.
Internally the buffer API is implemented as a chain of separate buffers.
This is done to avoid having to resize the existing buffer, which is
expensive. We keep track of where the reading currently is, and discard
the internal buffers after all the data in them is read.
Completions are basically a oneshot flag, which provide a `wait()` call
that blocks until 'finish()' has been called on the completion.
The nice aspect of completions is that because it is a oneshot the order
does not matter - if 'finish()' is called before 'wait()' then 'wait()'
returns immediately. It makes the logic for waiting until a thread is
done finishing up some work easy to implement.
This adds generic APIs to libqb for handling thread's, mutex's, and
condition variables. On Linux and OSX these are implemented via the ones
provided by pthreads. On Windows they're implemented via the ones
provided by the Win32 API.
For compiling, the code itself is not conditional, but the Makefile
includes logic to decide which implementation to pick.
Note that it would have been nice to simply use std::thread and friends
from C++11, however using them on MinGW appears to be a bit messy. Since
using the Windows ones directly isn't that hard this was an easy compromise.
This sets up a few different flags we'll need for the conditional
compiling, and also sets the C++ standard to gnu++11, which effectively
just matches what we were implicitly using before.
Note: Many files were removed (not yet existing/empty pages). The parser will try to download them on demand and will auto-generate text for missing pages (eg. most _gl pages).

searched.bin was added in error and should not show up when updating
./internal/source.
The symbol files are useless since the coresponding executable is not
something we preserve, and due to them changing practically every build
they result in unnecessary updates of ./internal/source
When building directly from the repo (either from a git clone or a
download of the zip of the repository) the version reported is very
misleading because it will not have a version label, suggesting it is
actually a 'release' version when in fact it could be anything.
The ./.ci/calculate-version.sh logic is already setup to delete an
existing ./internal/version.txt during a detected release build, so we
can just place one in the repositroy and it won't impact the versioning
of CI and release builds, but will show up when building locally.
Fixes: #63
Mostly old build scripts and helper files that are now covered by the
Makefile.
A notable deletion is the glew dll and lib files. These are unnecessary
because we compile `glew.c` directly rather than link against the dll or
lib copies we have.
Having windows call GetSystemMetrics without relying on glutGet, gets rid of the seg fault that can occur at program start up. screenicon was restored to it's previous state so that larger issues with it can be addressed at a future date.
Fixes the issue as brought up on the forums here: https://qb64phoenix.com/forum/showthread.php?tid=408
Also added a small set of logic so we don't end up inside an endless loop if the screen is hidden (via _SCREENHIDE), or if it doesn't exist for whatever reason.
This issue was fixed in 4d61ff79, but due to how ./internal/source is
updated the new ./internal/source files were compiled using a QB64
without the fix, producing files with the wrong quoting. Previously this
was worked around because the build process overwrote these files, but
the `Makefile` build requires them to be fixed.
./internal/source itself is fine, so it's easy enough to simply fix the
files by hand. Since ./internal/source now contains a compiled QB64 that
contains the fix from 4d61ff79 it's generated files will have proper
quoting and won't need to be manually updated.
