196050bd23 [common] framebuffer: improve client framebuffer read performance
Extensive profiling reveals that the glibc memcpy performs up to 2x
faster then the existing SIMD implementation that was in use here. This
patch also will copy large 1MB chunks if the pitch of the source and
destination match further increasing throughput.

7300d00f66 [common] option: handle ini lines without trailing newline
Before, if the last line of an ini file has no trailing \n, it is ignored.
This commit changes the parser to process such lines.

44bff58aa8 [common] option: ignore non-typeable ascii characters
Under windows text editors like to default to saving in UTF8 with a byte
order mask prefix preventing proper parsing of any option that is on the
first line of the file. Since the configuration file is only intended to
be plain ascii this change ignores all non-ascii characters solving this
issue.

f02d61d665 [host] dxgi: sleep until it's close to time to map
This change adds an average function to time how long it takes the GPU
to copy and map the texture, and then uses this average to sleep for 80%
of this average lowering CPU usage and potentially decreasing lock
contention.

f9a9953071 [client] egl: use new util_hasGLExt helper to check extensions
We previously used strstr, which can be prone to false positives when
the name of one extension is a substring of another extension.

This commit creates the helper function util_hasGLExt, which asserts
that the substring found in extension list is bounded by either spaces
or the beginning/end of the string.

fc7dd7dbb7 [common] cmake: correctly link static libbfd.a
When linking against libbfd.so, just passing libbfd.so to the compiler is
sufficient. When linking against the static version libbfd.a, however,
we must additionally link against libiberty.a and libz.a.

This commit adds a CMake helper to find the correct libraries that need
to be passed to link against libbfd correctly.

5ad70ccc41 [common] crash/linux: generate core dump when handling SIGSEGV
Calling abort() instead of exit() will generate a core dump, allowing gdb
to be used when the client crashes. This is desirable for the following
reasons:

1. gdb can be used to inspect the call stack with far more detail than the
   our quick stack trace code, and also allows the access to the heap.
2. Our SIGSEGV handler is unable to use debug symbols for shared libraries,
   making it impossible to debug bugs involving drivers and similar.

db16efe68b [common] add a reference counted buffer type
This allows buffers to be shared between different asynchronous operations.
Once all users no longer need the buffer, it will be freed.

The motivation for this is being able to stream Wayland clipboard data
asynchronously to multiple clients. The buffer should only be freed after
the clipboard has changed and all ongoing transfer completes.

62b27760ea [common] ivshmem: do not create dmabuf for simple mmap
It used to be the case that you need to create dmabuf for kvmfr devices
to be able to mmap them. But after #457, this is no longer needed.

Directly mmaping the kvmfr device has the advantage of avoiding the
creation of a dmabuf, which has cost (e.g. the list of pages, the
scatterlist, etc.).

a46a3a2668 [all] use explicit void parameter lists
This makes it a compile-time error to call a function that semantically
takes no parameters with a nonzero number of arguments.

Previously, such code would still compile, but risk blowing up the stack
if a compiler chose to use something other than caller-cleanup calling
conventions.

This is a major change to how the LG client performs it's updates. In

speed and/or frequency. This change allows LG to dynamically increase
it's FPS in order to better sync with the guest as it's rate changes.

bca54ab1f6 [client/host] added new asyncronous memory copy
This changes the method of the memory copy from the host application to
the guest. Instead of performing a full copy from the capture device
into shared memory, and then flagging the new frame, we instead set a
write pointer, flag the client that there is a new frame and then copy
in chunks of 1024 bytes until the entire frame is copied. The client
upon seeing the new frame flag begins to poll at high frequency the
write pointer and upon each update copies as much as it can into the
texture.

This should improve latency but also slightly increase CPU usage on the
client due to the high frequency polling.
