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.

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
and undo_no_t. Each type is still defined as dulint.
This is an initial step towards replacing dulint with a 64-bit data type.
Because modern compilers have no trouble supporting 64-bit arithmetics
even on 32-bit targets, the dulint struct is a relic that should go.
The last remaining major use of dulint is dictionary IDs
(table, index, and row ids).

recovery, tolerate clustered index records whose externally stored
columns have not been written. This should remove the assertion failures
that were reported as Mantis issue#58, issue#62, issue#64.
trx_is_recv(): New function: TRUE if this transaction is rolling back
an incomplete transaction in crash recovery.
enum trx_rbmode: Rollback modes: no rollback, normal rollback, crash recovery.
btr_cur_pessimistic_delete(), btr_free_externally_stored_field(),
btr_rec_free_externally_stored_fields():
Replace the ibool parameter with enum trx_rbmode.
btr_free_externally_stored_field(): If field_ref is zero, return
but assert ut_a(rbmode == RB_RECOVERY). Unless InnoDB has crashed
while inserting a clustered index record, field_ref should not be zero.
btr_rec_free_updated_extern_fields(): Add the parameter enum trx_rbmode.
btr_cur_pessimistic_update(): Pass the rbmode parameter to
btr_rec_free_updated_extern_fields().
row_undo_ins(), row_undo_mod_upd_del_sec(): If row_build_index_entry()
fails, assert trx_is_recv() and skip this secondary index.
row_undo_mod_upd_del_sec(): Empty the heap at the end of each loop
iteration in order to conserve memory and to reduce the number of
low-level memory allocations.
Change the format of TRX_IDs in INFORMATION_SCHEMA tables from DEC to
HEX.
The current TRX_IDs are hard to remember and track down: 426355, 428466,
428566, etc.
In HEX:
* there are less "digits", the strings are shorter;
* since there are 16 instead of 10 "digits", the chance of having
repeating ones are smaller.
The above look like 68173, 689B2, 68A16 in HEX.
