Linker response files for the MinGW and Unix makefile generators are
controlled by the variable QMAKE_LINK_OBJECT_MAX. This variable holds a
number. If the number of object files passed to the linker exceeds this
number, a linker response file containing object file paths is created.
This heuristic is extremely imprecise. It doesn't take into account the
length of object file names nor the length of $$OBJECTS_DIR.
Also, when using a static Qt, a big part of the linker command line are
libraries. A relatively small example can fail to link with "The
command line is too long" on Windows, even with the object files being
in a response file.
The MinGW makefile generator already reads the variable
QMAKE_RESPONSEFILE_THRESHOLD for compiler response files. Re-use this
variable for the linker response file of the Unix and MinGW makefile
generators.
If QMAKE_RESPONSEFILE_THRESHOLD is set, use it to determine whether to
create a response file. QMAKE_LINK_OBJECT_MAX is then ignored. The
response file contains objects and libraries.
If QMAKE_RESPONSEFILE_THRESHOLD is not set, use QMAKE_LINK_OBJECT_MAX to
determine whether to create a response file. The response file contains
only object files.
QMAKE_LINK_OBJECT_SCRIPT is used in both cases to specify a common base
name of all linker response files.

Setting the QMAKE_MANIFEST variable doesn't have
any effect for MSVC. This commit fixes that.
If the developer is setting this variable,
he/she will definitely use CONFIG-=embed_manifest_exe
or CONFIG-=embed_manifest_dll at the same time,
so I think there is no need to check this.

under windows, libraries can have a numeric suffix derived from VERSION,
and (under MinGW) a unix-like "lib" prefix - neither of which .prl files
have. therefore, we had to make the back-mapping from the library to the
.prl file reverse-engineer the original TARGET's name. we verify whether
we actually got the right file by comparing the target specified inside
the .prl file with what we started from.
this fixes linking of transitive deps of static deps.
the alternative of changing the .prl naming pattern to avoid the
back-mapping was discarded, as a) it would be backwards incompatible and
b) it would break project-internal -lfoo references to versioned libs.

these characters can appear in file names, but are meta characters in
dependency context. they have different semantics in make commands, so
this required some reshuffling in the windows generator (which just
treated dependencies and commands the same way).
we don't actually escape colons for nmake, because it has magic
treatment of drive letters anyway (and colons cannot appear elsewhere).
also, if a target's filename gets quoted, batch rules will blow up.
therefore, "funny" file names are really only supported as inputs -
which is just enough to make resource embedding work.

When building QNX on MS-Windows, make magically adds the Msys root as
prefix to variables whose values look like paths; this applies to both
environment variables and variables given values on the command-line.
When we don't actually want to install under the Msys root, this is
unwelcome "help". So (for MinGW's make) support a magic prefix of our
own, @msyshack@, that'll make a path value for INSTALL_ROOT not look
like a path to make; we can then strip it off when we come to use it.

instead of quoting more or less random variable contents early,
consistently quote everything only right before it is needed. this way
we can be sure that everything is correctly quoted, but not over-quoted.
this removed the need for the insanity that unescapeFilePath() and
similar ad-hoc contraptions were.
this had the somewhat counter-intuitive effect that it was possible to
remove escapeFilePath() calls from PBX::writeSettings() calls - these
were actually only unescaping.
[ChangeLog][qmake][Important Behavior Changes] A lot of quoting issues
have been fixed. As a side effect, qmake has become more sensitive to
over-quoted file names in project files.

On Windows, the application manifest file can be linked with the
executable, to specify for example the requested privileges of the
application. On MSVC nmake, the manifest is already handled in
NmakeMakefileGenerator::writeBuildRulesPart, but it is not compatible
with MinGW. On MinGW, this manifest file has to be referenced in the
Rc File. This patch simply handles the existing variable
"QMAKE_MANIFEST" which defines the appropriate line RT_MANIFEST in
the RC file.

this way QMAKE_LIBS{,_PRIVATE} can be treated the same as in all other
generators, which allows us to:
- make the windows generators' findLibraries() be more like the unix
version
- dispose of QMAKE_INTERNAL_PRL_LIBS handling while reading prl files
(because the output always goes to QMAKE_LIBS)
- as a side effect, QMAKE_LIBS_PRIVATE are not subjected to prl file
resolution any more, which is again consistent with unix - the
correctness of that needs to be assessed separately.
