Previously, we used ev_check watchers, which are executed at the beginning of an
event loop iteration.
This was problematic if one of the handlers happened to fill the XCB event
queue, e.g. by reading a reply from X11 and an event happened in the meantime.
In that situation, we would hand control to the event loop, entirely ignoring
the pending event. This would manifest itself as a 1-minute hang,
reproducible (sometimes) in the i3 testsuite.
issue #2790 describes an instance of this issue in i3bar, and we fixed that by
changing the watcher priority to run last. Handling events in xcb_prepare_cb has
the same effect, as ev_prepare watchers are run just before the event loop goes
to sleep.
The sender of the _NET_ACTIVE_WINDOW client message might know better when to
set focus than i3, as i3 does not know about unmanaged (override_redirect=1)
windows.

stbuf.st_size is of type off_t, which the standard defines as “extended signed
integral type”¹, and for which there is no correct printf format string. Hence,
we need to cast it into a hopefully-large-enough type (ugh) and use the
corresponding format string. In our case, int64_t should do it, as config files
really shouldn’t be anywhere close to those numbers.

Allow enabling forced focus wrapping by specifying "focus_wrapping
force" in i3's configuration. This syntax supersedes the previous
"force_focus_wrapping yes" one, which remains available for backwards
compatibility.
This fixes a crash that occurs when disabling floating for a container
while it is being moved or resized.
@Deiz describes the problem:
> It occurs because the command that disables floating runs before the
event loop. So, the window is tiled, its floating parent is destroyed,
but then a key event is handled which causes the position/size of the
now-destroyed parent to be modified.
Fixes#1627
Applied for:
1. '[...] focus' for a floating container raises it to the top.
2. Focusing a window through a focus event raises it to the top.
Fixes#2572
canonicalize_output_name allowed the "primary" special output name to
be canonicalized, thus converting it to the name of whatever output
was the primary output at the time. This caused settings
(specifically, i3bar output and tray_output settings) to be stored as
specific output names, instead of the intended special names whose
referred output may change as the system's configuration (i.e. current
primary output) changes.
Add a check to canonicalize_output_name to return the name as-is if it
is the special name "primary".
Allow appending 'P' to the fake output specification to set the
created output's "primary" flag, to allow writing test cases that
depend on the presence of a primary output.
fake_outputs_init would unconditionally increase the string read
pointer variable (walk) by one character more than the number of
characters that have been read, to skip past the character delimiting
records (a comma). However, when the input string was not terminated
by a comma, it would cause the function to read past the null
terminator instead.
Avoid this by explicitly checking for the expected delimiter.
fake_outputs_init used a sprintf invocation with a throw-away buffer
to estimate how many characters the sscanf invocation consumed. This
was unnecessary, and also potentially incorrect, as differences
between the read and formatted strings (such as leading zeros) could
lead to fake_outputs_init to lose its track.
Instead, use the %n format specifier which allows saving the number of
characters consumed by sscanf so far. %n is part of C99.
All other message types are verbs, only our first-ever message COMMAND wasn’t.
While we’re here, also change the message type dictionary into a table with
clickable links to the corresponding reply type.
Authors of downstream IPC libraries are encouraged to keep the old name around
so as to not break existing code, but mark it as deprecated.
This fixes a regression introduced in commit
4e88c10564ca5366c2578908f62ec56625a26718: when attempting to move the
single child of a container in the direction of another output, i3
would move the window to the output, despite the window not being at
the edge of its output, instead of moving it to its parent container.
The bug occurred because the check for moving containers across
outputs with non-default workspace layouts (issue #1603) did not
actually verify that the moved window lies at the edge of the
workspace, despite what its comment said.
Fixes issue #2466.
Makes "assign [<criteria>] workspace number <number>" work in the same
manner as "move to workspace number <number>" instead of assigning the
window to a workspace named "number <number>".
config.spec is modified to expect a 'number' string and an extra
argument is used in cfg_assign.
For workspaces that don't exist yet, workspace_get is used as a
fallback. This also allows the user to assign to "<number> <workspace>"
eg "2: work" and the full name will be used if workspace number 2
doesn't exist yet.
Fixes#2590.
This commit also introduces slurp() which reads a file in its entirety. Using
this function instead of doing IO in the functions in load_layout.c again and
again makes the code cleaner (fixing at least two memory leaks) and avoids
re-reading the same file 3 times.

Convert the output names specified in the "output" and "tray_output"
fields in bar blocks in i3's configuration to the referred output's
primary name. This allows specifying names other than the primary
output's name in the given fields without changing the IPC protocol.
In addition to the name of the monitor itself (which is still used as
the i3 output's primary name), register RandR output names associated
with the RandR monitor as alternative i3 output names.
Currently, only one name is ever added, and only the first name is
ever accessed; actually using the capability to store and access
multiple names comes in the following commits.
Currently simply returns output->name, but this will make it easier to
change how output names are stored in the following commits.
Also replace reading output->name with invocations of
output_primary_name. Code which writes output->name is unchanged. Done
using a mostly mechanical replacement of output->name to
output_primary_name(output).
