Merge tag 'v0.6.0' of git://git.libdivecomputer.org/libdivecomputer into Subsurface-branch

Sync up with upstream cersion 0.6.0. Annoying merge, mainly because a lof of the changes Jef had done are actually changes that came from our Subsurface branch, but in a different form, because Jef doesn't actually take patches directly from us. Why? I don't know. * tag 'v0.6.0' of git://git.libdivecomputer.org/libdivecomputer: Release version 0.6.0 Fix some potential buffer overflows Fix some casts with constant pointers Enable some useful compiler warnings by default Generate html documentation from the manpages Fix the decoding of the ndl/deco information Decode the firmware version for the iDive series Add support for the Suunto Eon Core Locate the most recent dive Add EON Steel time sync capability Improve the progress events Detect the model number using the hardware type Shearwater: add support for remaining gas time Shearwater: extract tank sensor data for log version 7 Shearwater: extract log version from header

+Version 0.6.0 (2017-11-24)
+==========================
+
+The v0.6.0 release adds support for several new devices, introduces two
+new features and fixes a couple of bugs. There are a few minor backwards
+incompatible changes, but most applications won't be affected by those.
+
+New features:
+
+ * Add support for new backends:
+    - g2: Scubapro G2, Aladin Sport Matrix, Aladin Square
+ * Add support for many new devices:
+    - Aqualung: i200, i750TC
+    - Cochran: Commander I, II and TM
+    - Cressi: Drake
+    - Hollis: DG02
+    - Mares: Quad
+    - Oceanic: F10
+    - Ratio: iX3M and iDive series
+    - Suunto: D4f, Eon Core
+    - Uwatec: Aladin Tec 3G
+ * Add basic timezone support
+ * Add support for synchronizing the device clock
+ * Document the public api with man pages
+
+Removed/changed features:
+
+ * Remove the deprecated gas change events
+ * Remove the deprecated vendor_product_parser_create(),
+   vendor_product_device_open() and vendor_product_extract_dives()
+   functions from the public api
+ * Remove the hw_{frog,ostc,ostc3}_device_clock() functions
+
+Bug fixes:
+
+ * Many small improvements

+# SYNOPSIS
+#
+#   AX_APPEND_COMPILE_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS], [INPUT])
+#
+# DESCRIPTION
+#
+#   For every FLAG1, FLAG2 it is checked whether the compiler works with the
+#   flag.  If it does, the flag is added FLAGS-VARIABLE
+#
+#   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
+#   CFLAGS) is used.  During the check the flag is always added to the
+#   current language's flags.
+#
+#   If EXTRA-FLAGS is defined, it is added to the current language's default
+#   flags (e.g. CFLAGS) when the check is done.  The check is thus made with
+#   the flags: "CFLAGS EXTRA-FLAGS FLAG".  This can for example be used to
+#   force the compiler to issue an error when a bad flag is given.
+#
+#   INPUT gives an alternative input source to AC_COMPILE_IFELSE.
+#
+#   NOTE: This macro depends on the AX_APPEND_FLAG and
+#   AX_CHECK_COMPILE_FLAG. Please keep this macro in sync with
+#   AX_APPEND_LINK_FLAGS.

+#
+#   AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
+#
+# DESCRIPTION
+#
+#   FLAG is appended to the FLAGS-VARIABLE shell variable, with a space
+#   added in between.
+#
+#   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
+#   CFLAGS) is used.  FLAGS-VARIABLE is not changed if it already contains
+#   FLAG.  If FLAGS-VARIABLE is unset in the shell, it is set to exactly
+#   FLAG.

+#   AX_REQUIRE_DEFINED(MACRO)
+#
+# DESCRIPTION
+#
+#   AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
+#   been defined and thus are available for use.  This avoids random issues
+#   where a macro isn't expanded.  Instead the configure script emits a
+#   non-fatal:
+#
+#     ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
+#
+#   It's like AC_REQUIRE except it doesn't expand the required macro.
+#
+#   Here's an example:
