The call to put IO threads to sleep was most probably meant for Windows
only as the comment in buf0rea.c suggests. However it was enabled on
all platforms. This patch restricts the sleep call to windows. This
approach of not putting threads to sleep makes even more sense because
now we have multiple threads working in the background and it probably
is not a good idea to put all of them to sleep because a user thread
wants to post a batch for readahead.

ChangeLog:
Follow the convention from the rest of the ChangeLog: for bugfixes from
bugs.mysql.com only the bug number and title goes in the ChangeLog. Detailed
explanation on what is the problem and how it was fixed is present in
the bugs database.

White-space fixup.

branches/zip: Fix bug# 46650:  Innodb assertion autoinc_lock == lock in lock_table_remove_low on INSERT SELECT

We only store the autoinc locks that are granted in the transaction's autoinc
lock vector. A transacton, that has been rolled back due to a deadlock because
of an AUTOINC lock attempt, will not have added that lock to the vector. We
need to check for that when we remove that lock.

move access to the this variable within a !UNIV_HOTBACKUP block.

after a successful operation, read innodb_table->flags from
the newly created table object, not from the old one that was just freed.

Approved by Sunny.

This is a non-functional change.

parameter partial. If savept==NULL, partial==FALSE.

do not tell Valgrind that the memory is free, to avoid
a bogus warning in Valgrind's built-in free() hook.

This should help track down Mantis Issue #289.

to avoid problems with Doxygen XML output.

Revert the dummy change from c5625.

(after resolving the conflict Makefile.am was not changed so I have made
a dummy change so I can commit and thus record that branches/5.1 has been
merged in branches/zip up to 5622):

Add a test program to check whether the PAUSE instruction is available.

Fixups in ChangeLog: sort filenames alphabetically and wrap to 78 chars per
line.

Change the read ahead parameter name to innodb_read_ahead_threshold.
Change the meaning of this parameter to signify the number of pages
that must be sequentially accessed for InnoDB to trigger a readahead
request.

      Bug #39802 On Windows, 32-bit time_t should be enforced
      
      This patch fixes compilation warning, "conversion from 'time_t' to 'ulong', 
      possible loss of data". 
      The fix is to typecast time_t to ulong before assigning it to ulong.

specific configuration.

Sun Studio

Those changes are contributed by Sun/MySQL. Two sets of changes
in this patch when Sun Studio is used:
- Explicit inlining of functions
- Prefetch Support

This patch has been tested by Sunny with the plugin statically
built in. Since we've never built the plugin as a dynamically
loaded module on Solaris, it is a separate task to change
plug.in.

Both srv_read_ahead_factor and srv_io_capacity should
be defined as ulong.

Approved by: Sunny

Non-functional change:
put files in noinst_HEADERS and libinnobase_a_SOURCES one per line and sort
alphabetically, so it is easier to find if a file is there or not and
also diffs show exactly the added or removed file instead of surrounding
lines too.

Add include/ut0auxconf.h to noinst_HEADERS
