Device:getDefaultRoute parses /proc/net/route and converts the hex
addresses to textual IP addresses, but in `isOnline` we don't care what
address the gateway actually has, we only care about whether we have a
default route into the Internet.
This provides a simpler alternative that does the equivalent of
"ip route get 203.0.113.1 || ip route get 2001:db8::1" (note that it
does support IPv6-only connectivity as opposed to
Device:getDefaultRoute) and returns true if we have a route.
Inspired by https://github.com/pavel-odintsov/get_default_outgoing_ip_linux
Doing the `isOnline` check (`socket.dns.toip("dns.msftncsi.com")`)
without having internet connectivity (`!isConnected`) results in the
`isOnline` check never succeeding again even if connectivity is later
acquired. This is most likely caused by /etc/resolv.conf only being
parsed once - https://sourceware.org/bugzilla/show_bug.cgi?id=984, an
issue that was fixed in glibc 2.26 (PocketBook firmware U740.6.8.2461
has glibc 2.23).
This fix works around the problem by checking if we have a default route
first before even attempting to check `isOnline`. If we don't, then
`isOnline` is (almost) guaranteed to fail anyway.
We could alternatively check `isConnected` instead, but that only checks
wireless connectivity on many platforms, and we could have internet
access via USBNet instead. Checking for the default route via any
interface should work reliably for both wireless and USBNet
connectivity.
Another alternative fix is to add a fallback nameserver to
/etc/resolv.conf like we do for the Kobo platform [1]. Unfortunately,
this fix would not work in the following (rather common) scenario:
1. PocketBook boots, connects to WiFi
2. KOReader starts, /etc/resolv.conf looks all right, no fallback needed
3. PocketBook goes to sleep, disconnects from WiFi, clears resolv.conf
4. PocketBook wakes up, stays disconnected
5. KOReader user does a Wikipedia lookup, networking freezes

Added in <https://github.com/koreader/koreader/pull/8722> and unproblematic for the past two years, but Weblate has now decided to complain about it to the extent of disabling translations:
> Error message
String contains control character: 'If some book titles, dictionary entries and such are not displayed well but shown as \ufffe\ufffe or ��, it may be necessary to download the required fonts for those languages. They can then be enabled as additional UI fallback fonts.\nFonts for many languages can be downloaded at:\n\nhttps://fonts.google.com/noto\n\nOnly fonts named "Noto Sans xyz" or "Noto Sans xyz UI" (regular, not bold nor italic, not Serif) will be available in this menu. However, bold fonts will be used if their corresponding regular fonts exist.'
Include in the EPUB stylesheet most of our epub.css
tweaks, so we get our expected styling even when
html5.css is used as the default stylesheet.
(Users liking the "web page" look can still get it
by enabling some of our existing style tweaks.)
- Reword and document most menu items.
- Handle internally two default styles, one applying only
to FB2/FB2 books, and the other to all other formats.
- Also don't reset the stylesheet to epub.css when
toggling Embedded Styles to off.
If there's only one contact, we won't get an ABS_MT_SLOT, so we need to
make sure we fall back to the main finger slot once we've caught a tool
switch.
Also, move the dedicated pen slot further away, so it has zero chance of
being detected as a potential buddy contact to a finger contact.
Fix#11514
When we open the document for the first time, the pan
positions are not being applied. If I use the bottom-to-top
mode we should see the bottom first, but the top is being
shown instead.
