format_text(alloc, string, strlen(string)) is a common idiom; provide
format_text_string(), which does the strlen(string) for you. (Any
string used in a %s to set the text of a protocol tree item, if it was
directly extracted from the packet, should be run through a format_text
routine, to ensure that it's valid UTF-8 and that control characters are
handled correctly.)
Update comments while we're at it.

We will use it later for other file formats, so that code such as the

(We should have a way to indicate whether the IDBs are real or fake, so

The QUIC transport protocol provides a stream, similar to HTTP/2. Make
it possible to look at the stream contents. This can be helpful while
HTTP/3 support is not yet complete.
Known issues that will be addressed in the future:
- If a single packet contains multiple streams, then Follow QUIC Stream
will wrongly include data from streams other than the selected one.
This is tracked by bug 16093 and affects HTTP/2 as well.
- The Substream index menu does not properly filter for available
stream numbers. If a non-existing stream is selected, then changing
to another (potentially valid) index results in the "Capture file
invalid." error. As workaround, clear the display filter first.
- Follow Stream always selects Stream ID 0 instead of the first or
currently selected stream field in a packet. Users should manually
update the stream index as needed.

On Windows, fstat() and stat() sets st_dev to different value depending
on whether it was called with file handle or file path. If file handle
was used, the st_dev is simply the file handle casted to unsigned.
If file path was used, then st_dev corresponds to drive letter
(A=0, B=1, C=2, ...).
Compare the files using the file index information retrieved by
GetFileInformationByHandle(). When compiled in configuration that
supports FILE_ID_INFO, the code first tries to obtain 128-bit FILE_ID_INFO
and if that fails, fallback to GetFileInformationByHandle().
