 . repo_commit calls out to fast_export to write the current commit to

   for a commit.

Provide macros to generate a type-specific treap implementation and
various functions to operate on it. It uses obj_pool.h to store memory
nodes in a treap.  Previously committed nodes are never removed from
the pool; after any *_commit operation, it is assumed (correctly, in
the case of svn-fast-export) that someone else must care about them.

Treaps provide a memory-efficient binary search tree structure.
Insertion/deletion/search are about as about as fast in the average
case as red-black trees and the chances of worst-case behavior are
vanishingly small, thanks to (pseudo-)randomness.  The bad worst-case
behavior is a small price to pay, given that treaps are much simpler
to implement.

Add a memory pool library implemented using C macros. The
obj_pool_gen() macro creates a type-specific memory pool.

The memory pool library is distinguished from the existing specialized
allocators in alloc.c by using a contiguous block for all allocations.
This means that on one hand, long-lived pointers have to be written as
offsets, since the base address changes as the pool grows, but on the
other hand, the entire pool can be easily written to the file system.
This could allow the memory pool to persist between runs of an
application.

For the svn importer, such a facility is useful because each svn
revision can copy trees and files from any previous revision.  The
relevant information for all revisions has to persist somehow to
support incremental runs.

ksh does not like it when the list argument is missing in a 'for' loop.
This can happen when NO_CURL is set which causes REMOTE_CURL_ALIASES to be
unset.  In this case, the 'for' loop in the Makefile is expanded to look
like this:

   for p in ; do

and ksh complains like this:

   /bin/ksh: syntax error at line 15 : `;' unexpected

The existing attempt to work around this issue, introduced by 70b89f87,
tried to protect the 'for' loop by first testing whether REMOTE_CURL_ALIASES
was empty, but this does not work since, as Johannes Sixt explains, "Before
the test for emptyness can happen, the complete statement must be parsed,
but ksh finds a syntax error in the statement and, therefore, cannot even
begin to execute the statement. (ksh doesn't follow POSIX in this regard,
where this would not be a syntax error.)".

Make's $(foreach) function could be used to avoid this shell glitch, but
since it has already caused a problem once before by generating a command
line that exceeded the maximum argument list length on IRIX, let's adopt
Bruce Stephens's suggestion for working around this issue in the same way
the OpenSSL folks have done it.  This solution first assigns the contents
of the REMOTE_CURL_ALIASES make variable to a shell variable and then
supplies the shell variable as the list argument in the 'for' loop.  This
satisfies ksh and has the expected behavior even if $(REMOTE_CURL_ALIASES)
is empty.
