6a90f6c5f0 * default MatrixBase ctor: make it protected, make it a static assert, only do the check when debugging eigen to avoid slowing down compilation for everybody (this check is paranoiac, it's very seldom useful) 
* add private MatrixBase ctors to catch cases when the user tries to construct MatrixBase objects directly

241b9d34a7 Hey, I was insomniac too ;) 
This restores much of the performance benefit of Euler's method, without compromising accuracy (tested on 1e+7 matrices). Namely, my benchmark now runs in 1.5 s instead of 2.2 s. The same in the default branch runs in 1.08 s instead of 1.9 s, so the default branch benefits even more!

9e15a6da2e Fix 4x4 matrix inversion. Applying Euler's trick is more tricky than what "high performance matrix inversion" websites would have you believe. Our 4x4 matrix inversion wasn't numerically stable, because in applying the Euler trick we didn't take the 2x2 block of biggest determinant. As a result, with float, we got relative errors above 1% every 1000 random matrices, and we got completely wrong results every 10000 matrices. 
Note that this decreases the performance, but we're still significantly faster than the brutal cofactors approach.

6173eb67ff really fix pkgconfig support and make install. 
* mistake: was using the install dir instead of binary dir
* was also using INCLUDE_INSTALL_DIR before it was set, so on a first cmake run, the pkgconfig file was bad

46f0fe3b4b SVD: 
* implement default ctor, users were relying on the compiler generater one and reported issues on the forum
* turns out that we crash on 1x1 matrices but work on Nx1. No interest in fixing that, so just guard by assert and unit test.

8084dbc86a copy the Memory.h file from the devel branch and remove some added trailing spaces. 
This is now very harmless to do as the big change (EIGEN_ALIGN preprocessor stuff and the body of ei_aligned_malloc) was already introduced in 2.0.6.

Should address Björn's issue, and also improve FreeBSD platform detection.

79ebba4f52 clean tags... 2.0.6 was tagged three times, with two different values. 
The best way to "push" a tag is to edit the .hgtags instead of using 'hg
tag xx' several times with the same value 'xx'.

ecf64d2dc3 Allow to override EIGEN_RESTRICT, to satisfy a smart ass blogger who claims 
that eigen2 owes all its performance to nonstandard restrict keyword.
well, this can also improve portability in case some compiler doesn't have __restrict.

6af2c2c67a backported the following to 2.0: 
* EIGEN_ALIGN and EIGEN_DONT_ALIGN and the corresponding logic in Macros.h
  (instead of using EIGEN_ARCH_WANTS_ALIGNMENT)
* The body of ei_aligned_malloc and ei_aligned_free

The reason for this backporting is that a user complained that with eigen 2.0 he got a warning at Memory.h:81 that the return value of posix_memalign was not used, and that function was declared with an attribute warn_unused_result.

Looking at this, it seemed that the body of this function was already overly complicated, and fixing this warning made it even worse, while the devel branch had a much simpler body and didn't suffer from that problem.

Then it was necessary to update ei_aligned_free too, and to backport EIGEN_ALIGN.

Inch' Allah....
