QFileWatcher is only reporting one path per signal which is suboptimal if
you change many files at once. This patch is introducing a timer which is
waiting some time time to see if more path changes are reported and is
collecting them in a vector.

Compiling every header file again and again is quite time comsuming. There
are technics to improve this like preambles(a kind of automated
precompiled header) but they don't share their data between translation
units. This approach provides an automatically generated precompiled
header for every project and subproject to improve the loading time.

Slow and very slow tests have now their own test category. We add SlowTest
for tests which are slower than ~5ms and VerySlowTest if they are slower
than ~100ms. They are disabled them by "-*SlowTest.*". If you have a faster
machine than most developers simply try lower values. The aim is that most
developers can execute the tests in under ~2s.
In the long run we should use dependency breaking and data sharing to
reduce the count of the slow tests.

and we will create two project parts, one where it is a CHeader, the

Parsing happens rotationally on the translation units.
The recently parsed translation unit is used for completion jobs while
the older version is used for parse jobs.
Advantages:
A1. A completion job cannot be blocked anymore by currently running
parse job.
A2. Faster triggering of parse jobs. A reparse was triggered about
1650ms after the last keystroke. This is down to 500ms now since we
do not have a blocking translation unit for the completion anymore.
Disadvantages:
D1. Memory consumption is doubled for an edited document.
This could be addressed by suspending the second translation unit
after some time of inactivity.
D2. Setup of the supportive translation unit takes some time.

We queried the translation unit for the source location of the dot

source locations for the translation unit. And we do not want to reparse
since this is expensive. Thus, determine the byte position manually by
scanning over the document until the right line/column is reached.

1 struct Foo { int member; };
2 void f(Foo *foo)
3 {
4 foo.<REQUEST COMPLETION> // correct '.' to '->' and provide results
5 }
The preferred approach would be to check if "foo" in line 4 is of
pointer type, but there is no suitable cursor (only CompoundStmt) at
that position since the code is usually not yet parsed and thus invalid.
Thus, just run the completion as is. If there are not any results for a
dot completion, re-run the completion with "." exchanged by "->". This
approach is inherently slower than the preferred approach implemented in
the built-in code model.
The following rare cases are not handled:
1) Requesting completion after white space:
Works: foo.<COMPLETE HERE>
Fails: foo. <COMPLETE HERE>
2) Opening a file and requesting completion (ctrl+space) without prior
editing. No editing before triggering completion means that no
unsaved file is generated on the backend side, which is a
requirement for the correction.
