11fd7ffb21 acinclude.m4: fix configure tests broken with Clang 16 (implicit function declarations) 
Clang 16 will make -Wimplicit-int and -Wimplicit-function-declaration
errors by default which can, in addition to other things, lead to
some configure tests silently failing/returning the wrong result.

For more information, see LWN.net [0] or LLVM's Discourse [1], gentoo-dev@ [2],
or the (new) c-std-porting mailing list [3].

8d7db37efc For sixel, no need to round image size to multiple of character size. 
With this fix combined with fix to libsixel:

https://github.com/saitoha/libsixel/pull/170

browsing on slow machines (e.g., when floating-point calculation is
emulated by kernel) gets significantly speed up.

Note that if i->cache->a_width (i->cache->a_height) is zero, width
(height) should be set to zero. Otherwise, image in screen boundary
(i.e., partially displayed) becomes strangely resized.

01b8ac418b Display resized image for OSC 5379 (mlterm). 
Previously, some images, e.g., Google logo on its top page, are not
displayed at all for OSC 5379 (mlterm).

8f3fcecc43 Retry if loading of a file fails 
This fixes GH issue #210, Debian BTS #537761[1] and obsoletes Debian
BTS #946440[2].

File names like 'a#a.html', 'b?b.html' or 'c%20.html' can not be opened
without using '-o argv_is_url=1' as the file name is interpreted as a
local URL.

If everything fails and argv_is_url is not set retry as a local file.

4486ac99bc Add GitHub Action to build source when pushing 
Let's at least ensure that the source builds without warnings.

The build image used, Ubuntu, spits out quite some warnings about
ignored return values. Use '-Wno-unused-result' for now.

The configure options are chosen to resemble the default Debian version.

9192ed59db Add option to set directory for temporary files 
With this patch applied the user can configure a directory to store
temporary/cache files. The history and cookies remain in RC_DIR.

I suppose the intent of writing the history to a temp file first is to
make the actual write an atomic operation. As rename() does not work
across mount points, we need to handle the temp file for the history
different to keep this behaviour.

Add a new type for the temp history file and handle this case different
when creating a temp file.

9f5c311e45 Do not call fclose() on a NULL pointer 
The if clause is true if cache is NULL. man 3 fclose says:

  The  behaviour  of  fclose() is undefined if the stream parameter is an
  illegal pointer, or is a descriptor already passed to a previous  invo‐
  cation of fclose().

Check if cache is NULL before calling fclose().

22d1fb47ac Remove null pointer dereference 
This if is only true if both strchr return NULL, making sure that *q is
a NULL dereference.

The intention was to remove trailing '>' (or '\t') from the message-id
(p) for add_news_message().

Adjust the condition.

9a2b86088c Fix broken anchor with link number at EOL 
If, while adding the link number, we detect that we need to flush the
line, the anchor will be broken. When returning to the last breakpoint
only the link number will be removed, the internal anchor reference '<a
hseq=... >' remains on the flushed line.

Instead of adding the link number in a separate operation, check if we
just processed an anchor tag and prepend the current token with the link
number.
