Color profiles not loaded on Windows

Bug Description

Reproduced on Windows XP (32-bit) with lp:inkscape/0.92.x rev. 15214.
Not reproduced on Xubuntu 16.04, lp:inkscape/0.92.x rev. 15214 and lp:inkscape rev. 15273.

On Windows XP, the profiles linked to a document are listed in the Documents properties and F&S dialogs, but can't be used. It seems to be due to bug in src/uri.cpp (called from src/color-profile.cpp, ColorProfile::set method).

The document docbase is "C:\Documents and Settings\nicolas\Bureau\SVG\profiletest.svg" and xlink:href="C:\WINDOWS\System32\spool\DRIVERS\COLOR\is330.icm" (only one profile to keep the example as simple as possible).

In ColorProfile::set:
1. "g_uri_escape_string" returns an escaped path for the profile:
2. In "URI::from_native_filename", the path is then turned into an uri with "g_filename_to_uri":
and then initialized as an URI object.
3. "URI::getFullPath" is called for the docbase URI object, and itself calls "_impl->getPath()" that returns:
"/C:/Documents and Settings/nicolas/Bureau/SVG/profiletest.svg"
4. "URI::getFullPath" tests the path, and as it's an invalid path, clears it.
5. Another URI object is created for the profile path. "_impl->getPath()" returns:
Invalid again, the path is clears.
6. "cmsOpenProfileFromFile" tries to open an empty path, and fails, but an empty (and completely useless) color profile is created with a correct name anyways.

gchar* fullname = g_uri_unescape_string(fullpath.c_str(), "");
gchar* fullname = g_uri_unescape_string(escaped, "");
fixes the issue on Windows XP, with profiles linked as absolute path. But of course, it would be better to fix the issue in the URI creation.

Another possibility to fix the profile path (but not the docbase). More elegant, but really needs some extra testing.

Apparently, removing ":" from the reserved_chars_allowed list seems to work correctly.

The "g_uri_escape_string" part was added when fixing bug #437927 "crash in 'Fill > CMS' tab when linked icc color profile name contains spaces ". Does anyone know why we used such a long list?
