  Preparation for the fix of
  Bug#45097 Hang during recovery, redo logs for doublewrite buffer pages

  Non-functional change: move FSP_* macros from fsp0fsp.h to a new file
  fsp0types.h. This is needed in order to be able to use FSP_EXTENT_SIZE
  in mtr0log.ic.

  Preparation for the fix of
  Bug#45097 Hang during recovery, redo logs for doublewrite buffer pages

  Do not include unnecessary headers mtr0log.h and fut0lst.h in trx0sys.h
  and include fsp0fsp.h just before it is needed. This is needed in order
  to be able to use TRX_SYS_SPACE in mtr0log.ic.

  Fix Bug#45097 Hang during recovery, redo logs for doublewrite buffer pages

  Do not write redo log for the pages in the doublewrite buffer. Also, do not
  make a dummy change to the page because this is not needed.

There is nothing for Doxygen to see in this file, move along.

to prevent bogus Doxygen errors.

that is, make Doxygen ignore these test programs.

/*********************************
comments to Doxygen /** style like this:
/*****************************//**

This conversion was performed by the following command:

perl -i -e 'while(<ARGV>){if (m|^/\*{30}\**$|) {
s|\*{4}$|//**| if ++$com>1; $_ .= "\@file $ARGV\n" if $com==2}
print; if(eof){$.=0;undef $com}}' */*[ch] include/univ.i

This is to avoid triggering an error in Doxygen.

This patch was created by running the following commands:

for i in */*[ch]; do doxygenify.pl $i; done
perl -i -pe 's#\*{3} \*/$#****/#' */*[ch]

where doxygenify.pl is
https://svn.innodb.com/svn/misc/trunk/tools/doxygenify.pl r510

Verified the consistency as follows:

(0) not too many /* in: */ or /* out: */ comments left in the code:
grep -l '/\*\s*\(in\|out\)[,:/]' */*[ch]

(1) no difference when ignoring blank lines, after stripping all
C90-style /* comments */, including multi-line ones, before and after
applying this patch:

perl -i -e 'undef $/;while(<ARGV>){s#/\*(.*?)\*/##gs;print}' */*[ch]
diff -I'^\s*$' --exclude .svn -ru TREE1 TREE2

(2) after stripping @return comments and !<, generated a diff and omitted
the hunks where /* out: */ function return comments were removed:

perl -i -e'undef $/;while(<ARGV>){s#!<##g;s#\n\@return\t.*?\*/# \*/#gs;print}'\
 */*[ch]
svn diff|
perl -e 'undef $/;$_=<>;s#\n-\s*/\* out[:,]([^\n]*?)(\n-[^\n]*?)*\*/##gs;print'

Some unintended changes were left.  These will be removed in a
subsequent patch.

Whitespace fixup.

Document the function parameters.

srv0start.c does not (any longer) call memcmp.
srv_parse_megabytes(): Add a function comment.

transactions that are started before the rollback of incomplete
transactions has finished may have an inconsistent view of the
secondary indexes.

dict_index_is_sec_or_ibuf(): Auxiliary function for controlling

secondary index or the insert buffer tree.

lock_rec_insert_check_and_lock(),
lock_sec_rec_modify_check_and_lock(), btr_cur_ins_lock_and_undo(),
btr_cur_upd_lock_and_undo(): Add the parameter mtr.

page_set_max_trx_id(): Allow mtr to be NULL.  When mtr==NULL, do not
attempt to write to the redo log.  This only occurs when creating a
page or reorganizing a compressed page.  In these cases, the
PAGE_MAX_TRX_ID will be set correctly during the application of redo
log records, even though there is no explicit log record about it.

btr_discard_only_page_on_level(): Preserve PAGE_MAX_TRX_ID.  This
function should be unreachable, though.

btr_cur_pessimistic_update(): Update PAGE_MAX_TRX_ID.

Add some assertions for checking that PAGE_MAX_TRX_ID is set on all
secondary index leaf pages.
