The pop_cstring() function is used by the git parser to
duplicate a quoted string. On error, it returns an empty
string literal. Since the caller expects a copied string
and takes ownership of that string, it will ultimately
be freed.
Concrete example: a log with erroneous cylinder data was opened
getting such an empty string literal as description. On closing or
syncing with the cloud, the dive is freed, leading to a free
of the string literal -> crash.
Return a copy of the empty string instead.

If the user tries to download from a device that he hasn't given the app
permission to read from, Android will pop up a dialogue asking for that
permission. With this after giving the permission we continue (well,
technically, restart) the download which is likely the expected behavior.

The usbRescan() code is smart enough not to duplicate entries that might
already be there. And with this the user doesn't have to manually tap
rescan if they didn't open Subsurface-mobile via the intent after a
device was plugged in.

This way even if a USB device wasn't added through an Android intent, we
still have a way to scan for it and select it. This is especially
important in case a user has a cable that we haven't seen yet (i.e. with
a VID/PID that we haven't added to Subsurface-mobile), but that
nevertheless works with the android usb serial drivers.
This also makes the flow a little more logical / consistent when
deciding which connections to show.

This finally allows us to download from not just the first device, but specifically
the device that the user picks.
Passing the object through a void pointer is not nice - but since this traverses
C code other solutions (like passing an index into the list) seemed even worse.

If the user hadn't granted USB permissions, yet, we asynchronously get informed

We now always create a list of usb devices that doesn't list a driver

for devices that are unknown to us.

When a user is downloading from a DC for the first time (without using
the "usb device connected" popup), the user is requested to grant
permission to use the USB device.
This is done asynchronously, thus the download is aborted. To be more
user-friendly, we now react to the intent with the "usb granted" result.
The plan here is to start the download again.

As discussed in issue #2657, there are now more fields about the usb
device information in android_usb_serial_device_descriptor.
Additionally, the user-facing string now makes more sense:
"vendor [<bus# as integer>:<dev# as integer>]"
Where vendor is as reported by android, but shortened to 16 characters.
Examples:
FTDI [1:2]
Silicon Labs [1:4]

This commit contains the serial_android_usb part of the changes proposed
in issue #2657.
What's implemented:
- A data structure that contains all the data that can be used to
describe an usb device (including user-facing string).
- A function to get a list of all attached usb devices (optionally with
selectable driver class).
- Changes in the serial_android_usb_open-function and in the Java part
to use the information about the usb device and optionally selected
driver when connecting.
This commit keeps compatibility with the current UI-Code in the case
that only one USB-Device is connected. If two devices are connected,
only the first one is tried.
There are still some small things to do:
- Change the user-facing string to something more descriptive.
- Parts which aren't uesd anymore when the UI-Part is implemented are
simply marked as obsolete (to keep compatibility for now).
But generally it seems to work.

This is the exact same case as the previous commit, just for the writing
side.
Once again, it's the subsurface rfcomm iostream code that can return
DC_STATUS_SUCCESS with a byte count of zero when something goes wrong
with the write.
And once again, our libdivecomputer iostream code didn't try to be
robust and protect itself from that case.
The fix is equivalent, although slightly simpler, since the write side
doesn't have the whole timeout issue.
Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
We had two independent bugs here, both of which needed to fire for this
to cause a problem. This fixes both of them.
The first bug was that our rfcomm code would return DC_STATUS_SUCCESS
with a zero-sized read when a timeout happened, or when the rfcomm
socket had disconnected. That makes absolutely no sense. We should
return DC_STATUS_TIMEOUT on timeout, and DC_STATUS_IO if the socket has
disconnected without any data.
The fix to this is to make the whole rfcomm iostream read logic much
simpler: there's no need to loop at all for partial results, because the
libdivecomputer iostream side will do the loop for us (and handle
partial results much better: it knows if the target backend can handle
those partial results or not).
The second bug was in our libdivecomputer iostream read() function,
which reacted very badly to this bad return value. This updates our
libdivecomputer branch to one that is more careful about things.

The diveListNotifier.divesSelected() signal is used to inform the
models of a selection change. It sent the current dive as a second
parameter. This is redundant, because the only sender of the signal
sets current_dive just before sending the signal. Remove the
parameter, which appears to be an artifact.

This was a merge error in the dive list rewrite and brought in a code block that
had moved, which caused issues with correctly switching to the dive list.
Calling setupActions() moves to the diveListView (where it really belongs).
Instead of messing with the visibility of components of the same page, we now
simply switch out the shown page.
