In shared memory functions take as parameters pinters to structures instead
of void pointers. By this compiler will warn when wrong type of pointer is
passed. For example when pointer to the data in shmem is passed instead of
pointer to the header.

Check the consistency of shmem during opening with wrs_shm_get_and_check.
It was possible that sequence number was increased during the opening, but it
was interpreted as version error.

Add defines describing different return errors.

This change is backward compatible.

Keep explicitly lock bit in the sequence variable as a LSB bit.
This solution is backward compatible. The difference is only when shmem is
lock twice. Before it was treated as unlocked, now still as a lock.

Remove excessive locks from the function delete_htab_entry.
Function rtu_fd_commit is always guarded with shmem lock. The function
rtu_fd_commit calls rtu_hw_commit, which calls delete_htab_entry. By this
function wrs_shm_write with a parameter WRS_SHM_WRITE_BEGIN was called twice
before it was called twice with a parameter WRS_SHM_WRITE_END.

PHP code of the web interface was updating values of "upload_max_filesize"
and "post_max_size" in the /etc/php.ini. Besides it is extremely bad idea to
do that, such changes to take place require restart of lighttpd, which was
never performed. Luckily after the update of /etc/php.ini it was also copied
to flash at the location /usr/etc/php.ini. Because of this update via
webinterface worked only when:
--firmware.php was opened via web browser
--restart of a switch was performed

The fix contains a patch to set these values in the php.ini and remove
the update of php.ini by php code.

This will allow users to have special configuration (that is not possible to
achieve by just using dot-config) without a need to manually handle custom
script.

The script can be used from /wr/bin/custom_boot_script.sh or downloaded during
the boot. It is not possible to execute a script which was downloaded during
the previous boot. But a script can be written in such way to copy itself to
/wr/bin/custom_boot_script.sh.
