Stephen Kelly 116459d34f cmListCommand: Avoid needlessly erasing from vectors.
The entire vector will be destroyed at once at the end of the scope,
and the remove algorithms already give us the end of the range of
interesting values, so just use those sentinals.

Stephen Kelly cebeed2486 cmAlgorithms: Add cmRemoveDuplicates algorithm.
Start by creating a vector to hold a unique values of the input range.  We
expect that in most cases, there will be relatively few duplicates, so
reserving enough memory for a complete copy is worthwhile.  Unlike a solution
involving a std::set, this algorithm allocates all the memory it needs
in one go and in one place, so it is more cache friendly.

Populate the unique copy with a lower_bound insert algorithm and record the
indices of duplicates.  This is the same complexity as the std::set insert
algorithm, but without the need to allocate memory on the heap and other
disadvantages of std::set.

Remove the duplicates with the cmRemoveIndices algorithm.

Stephen Kelly 050958a328 cmAlgorithms: Add cmRemoveMatching algorithm.
Implement it in terms of std::remove_if with a binary search through
a matching range.

Stephen Kelly 6a22e40147 cmListCommand: Use cmRemoveIndices for REMOVE_AT subcommand.
Avoid repeatedly looping over the indices to process elements (even
without breaking out of the loop when the element is found).

Stephen Kelly 0b5cf0dabd cmAlgorithms: Implement algorithm for removing indexes.
Implement ContainerAlgorithms::RemoveN to remove N elements to the
end of a container by rotating.  The rotate is implemented in terms
of the efficient swap algorithm, optimized even more in the standard
library implementation when the compiler supports the rvalue-references
feature to move elements.  Implement cmRemoveN with a Range API
for completeness.

std::rotate in C++11 is specified to return an iterator, but
c++98 specifies it to return void.  libstdc++ 5.0 will be the first
version to have the correct return type.  Implement
ContainerAlgorithms::Rotate in terms of std::rotate and return the
correct iterator from it.  While std::rotate requires forward iterators,
 this workaround means cmRotate requires bidirectional iterators.  As
most of CMake uses random access iterators anyway, this should not
be a problem.

Implement cmRemoveIndices in terms of the RemoveN algorithm, such
that each element which is not removed is rotated only once.  This
can not use the cmRemoveN range-API algorithm because that would
require creating a new range, but the range must be taken by reference
and so it can't be a temporary.

These remove algorithms are not part of the STL and I couldn't find them
anywhere else either.

Stephen Kelly 1cecd3a531 cmListCommand: Use std::find algorithm for FIND subcommand.
Use a ostringstream to account for the input being a variable of type
size_t as a result of using std::distance.  There is no single
format string which portably accepts a size_t.

Stephen Kelly 2c4a7298fc cmMacroCommand: Declare arg in the scope that it is used.
It can make sense to declare objects outside of loops if
the size required by the object can grow (eg std::string when
using getline), but that is not the case here.
