626172a16b libcamera: Drop file name from header comment blocks
Source files in libcamera start by a comment block header, which
includes the file name and a one-line description of the file contents.
While the latter is useful to get a quick overview of the file contents
at a glance, the former is mostly a source of inconvenience. The name in
the comments can easily get out of sync with the file name when files
are renamed, and copy & paste during development have often lead to
incorrect names being used to start with.

Readers of the source code are expected to know which file they're
looking it. Drop the file name from the header comment block.

The change was generated with the following script:

----------------------------------------

dirs="include/libcamera src test utils"

declare -rA patterns=(
	['c']=' \* '
	['cpp']=' \* '
	['h']=' \* '
	['py']='# '
	['sh']='# '
)

for ext in ${!patterns[@]} ; do
	files=$(for dir in $dirs ; do find $dir -name "*.${ext}" ; done)
	pattern=${patterns[${ext}]}

	for file in $files ; do
		name=$(basename ${file})
		sed -i "s/^\(${pattern}\)${name} - /\1/" "$file"
	done
done
----------------------------------------

This misses several files that are out of sync with the comment block
header. Those will be addressed separately and manually.

81e7689bb1 libcamera: stream: Turn StreamRole into scoped enumeration
The StreamRole enum has enumerators such as 'Raw' that are too generic
to be in the global libcamera namespace. Turn it into a scoped enum to
avoid namespace clashes, and update users accordingly.

da0dd36149 gstreamer: Omit extra semicolons
Macros used in gstreamer (e.g. G_DEFINE_TYPE) are functions. The
end semicolons with the macros are unnecessary.

f976eb5cb6 libcamera: Remove void specifier for functions that take no arguments
In C++, unlike in C, a function that takes no argument doesn't need to
specify void in the arguments list. Drop the unnecessary specifiers.

0c4147c3b6 gst: libcamerasrc: Implement timestamp support
This is an experimental patch adding timestamp support to the libcamerasrc
element. This patch currently assume that the driver timestamp are relative to
the system monotonic clock. Without a reference clock source, the timestamp are
otherwise unusable, and without timestamp only minor use case can be achieved.

d1d1348228 gst: libcamerasrc: Implement initial streaming
With this patch, the element is now able to push buffers to the next
element in the graph. The buffers are currently missing any metadata
like timestamp, sequence number. This will be added in the next commit.

5d6db0936f gst: pad: Add method to store retrieve pending buffers
These will be useful for streaming. The requestComplete callback will
store the buffers on each pads so that the _run() can pick them up
and push them through the pads from a streaming thread.

71a28f9593 gst: Add pads to the source
This simply adds the boiler plate for pads on the source element. The
design is that we have one pad, called "src", that will always be
present, and then more pads can be requested prior in READY or less
state. Initially pads have one property "stream-role" that let you
decide which role this pad will have.
