The memory management and string concatenation was hard to follow.
Since the mobile files ios.cpp and android.cpp were already
converted to C++, let's do the same for Unix, Windows and MacOS.
Simply store the default directory and filename in a function-level
static string. Thus, it will be initialized on first call and
freed on application exit. Since the std::string data is
guaranteed to be contiguous and zero-terminated, it can be used
from C code.

While having the local user information in the repo on Linux seemed
clever when we implemented it, it's inconsistent with all the other
platforms. Let's just not do that unless the user has indeed set
a global name/email pair for git.
Instead indicate if this was Subsurface or Subsurface-mobile.

The native buffer of a membuffer is not NUL-terminated, so when you want
to detach it and use it as a C string, you had to first do
'mb_cstring()' that adds the proper termination/
This was all documented in the header files, and all but two users did
it correctly.
But there were those two users, and the exported interface was
unnecessarily hard to use. We do want the "just detach the raw buffer"
internally in the membuffer code, but let's not make the exported
interface be that hard to use.
So this switches the exported interface to be 'detach_cstring()', which
does that 'mb_cstring()' for you, and avoids the possibility that you'd
use a non-terminated memory buffer as a C string.
The old 'detach_buffer()' is now purely the internal membuffer
implementation, and not used by others.

A number of architecture-dependent functions were declared in
dive.h. Move them to file.h so that not all file-manipulating
translation units have to include dive.h. This is a small step
in avoiding mass-recompilation on every change to dive.h

When no real name is set in /etc/passwd the username ends
up being ",,,". Git does not like that. Actually, only the
part before the first comma is the name, the rest is office
and phone number. We don't want those.
Before we only testing for the username being a NULL pointer.

This removes some special-case code for Uemis, replacing it with simply
passing in the device transport information.
This makes device enumeration work for the Garmin Descent (if it is
listed by libdivecomputer as a USB storage device, that is).
I don't actually do any of the libdivecomputer parsing yet, and only
have a stub for the Garmin Descent, but now the directory selection
works with that stub. The actual download obviously does not.

The logic for finding a mount point for the Garmin FIT devices is
basically exactly the same as for the UEMISSDA, even if the rest of the
sequence is not the same.

The compiler complained about assigning the "const char *" returned by
mb_cstring() to a "char *". The warning is correct, as the returned
buffer still belongs to the membuffer. The code only worked because
destruction of the membuffer was "forgotten".
Fix this by using the "detach_buffer()" function, which passes ownership
to the caller and accordingly returns a "char *".
