Merge upstream libdivecomputer updates from Jef Driesen:

 - Jef merged the EON Steel dive sorting fix we had in our branch: one
   less difference to upstream

 - Jef merged the McLean Extreme support with some updates and cleanups,
   this just takes all his changes.

 - manual pages for iostream

 - various minor fixes and updates from Jef

* git://github.com/libdivecomputer/libdivecomputer:
  Update the gitignore file
  Update the man pages for the new iostream functions
  Purge the serial port buffer during initialization
  Add support for the McLean Extreme
  Suunto Eon Steel: sort the dive list properly
  Remove the salinity compensation
  Fix the hwOS ppO2 bug for firmware v3.08

Iterates through the available USB HID devices matching the given
.Fa descriptor .
Accepts a
.Fa context
opened with
.Xr dc_context_new 3
and a
.Fa descriptor
usually found by searching through
.Xr dc_descriptor_iterator 3 .
.Pp
On returning
.Dv DC_STATUS_SUCCESS
the

.Xr dc_iterator_next 3 .
.Pp
The value type of the iterator is of type
.Ft dc_usbhid_device_t .
This value can be used in functions to extract information about this specific USB HID device, namely
.Xr dc_usbhid_device_get_pid 3
and
.Xr dc_usbhid_device_get_vid 3 .
When done the USB HID device needs to be freed with
.Xr dc_usbhid_device_free 3 .
.Pp
After iterating the
.Fa iterator
needs to be freed using
.Xr dc_iterator_free 3 .
.Sh RETURN VALUES
Returns
.Dv DC_STATUS_SUCCESS
on success, or another

code on failure.
On
.Dv DC_STATUS_SUCCESS
the returned
.Fa iterator
needs to be freed when done using
