/**
Skip trailing space.
On most systems reading memory in larger chunks (ideally equal to the size of
the chinks that the machine physically reads from memory) causes fewer memory
access loops and hence increased performance.
This is why the 'int' type is used : it's closest to that (according to how
it's defined in C).
So when we determine the amount of whitespace at the end of a string we do
the following :
1. We divide the string into 3 zones :
a) from the start of the string (__start) to the first multiple
of sizeof(int) (__start_words)
b) from the end of the string (__end) to the last multiple of sizeof(int)
(__end_words)
c) a zone that is aligned to sizeof(int) and can be safely accessed
through an int *
2. We start comparing backwards from (c) char-by-char. If all we find is
space then we continue
3. If there are elements in zone (b) we compare them as unsigned ints to a
int mask (SPACE_INT) consisting of all spaces
4. Finally we compare the remaining part (a) of the string char by char.
This covers for the last non-space unsigned int from 3. (if any)
This algorithm works well for relatively larger strings, but it will slow
the things down for smaller strings (because of the additional calculations
and checks compared to the naive method). Thus the barrier of length 20
is added.

@param len the length of the string

This macro defines whether the compiler in use needs a 'typename' keyword
to access the types defined inside a class template, such types are called
dependent types. Some compilers require it, some others forbid it, and some
others may work with or without it. For example, GCC requires the 'typename'
keyword whenever needing to access a type inside a template, but msvc
forbids it.

This structure is used to define bind information, and
internally by the client library.
Public members with their descriptions are listed below
(conventionally `On input' refers to the binds given to
mysql_stmt_bind_param, `On output' refers to the binds given
to mysql_stmt_bind_result):
buffer_type - One of the MYSQL_* types, used to describe
the host language type of buffer.
On output: if column type is different from
buffer_type, column value is automatically converted
to buffer_type before it is stored in the buffer.
buffer - On input: points to the buffer with input data.
On output: points to the buffer capable to store
output data.
The type of memory pointed by buffer must correspond
to buffer_type. See the correspondence table in
the comment to mysql_stmt_bind_param.
The two above members are mandatory for any kind of bind.
buffer_length - the length of the buffer. You don't have to set
it for any fixed length buffer: float, double,
int, etc. It must be set however for variable-length
types, such as BLOBs or STRINGs.
length - On input: in case when lengths of input values
are different for each execute, you can set this to
point at a variable containining value length. This
way the value length can be different in each execute.
If length is not NULL, buffer_length is not used.
Note, length can even point at buffer_length if
you keep bind structures around while fetching:
this way you can change buffer_length before
each execution, everything will work ok.
On output: if length is set, mysql_stmt_fetch will
write column length into it.
is_null - On input: points to a boolean variable that should
be set to TRUE for NULL values.
This member is useful only if your data may be
NULL in some but not all cases.
If your data is never NULL, is_null should be set to 0.
If your data is always NULL, set buffer_type
to MYSQL_TYPE_NULL, and is_null will not be used.
is_unsigned - On input: used to signify that values provided for one
of numeric types are unsigned.
On output describes signedness of the output buffer.
If, taking into account is_unsigned flag, column data
is out of range of the output buffer, data for this column
is regarded truncated. Note that this has no correspondence
to the sign of result set column, if you need to find it out
use mysql_stmt_result_metadata.
error - where to write a truncation error if it is present.
possible error value is:
0 no truncation
1 value is out of range or buffer is too small
Please note that MYSQL_BIND also has internals members.

Protocol stages
---------------
A client following the MySQL protocol goes through several stages of it. Each
stage determines what packets can be expected from the server or can be send
by the client.
Upon receiving each trace event, trace plugin will be notified of the current
protocol stage so that it can correctly interpret the event.
These are the possible protocol stages and the transitions between them.

/**
@file
my_snprintf service
Portable and limited vsnprintf() implementation.
This is a portable, limited vsnprintf() implementation, with some
extra features. "Portable" means that it'll produce identical result
on all platforms (for example, on Windows and Linux system printf %e
formats the exponent differently, on different systems %p either
prints leading 0x or not, %s may accept null pointer or crash on
it). "Limited" means that it does not support all the C89 features.
But it supports few extensions, not in any standard.
my_vsnprintf(to, n, fmt, ap)
@param[out] to A buffer to store the result in
@param[in] n Store up to n-1 characters, followed by an end 0
@param[in] fmt printf-like format string
@param[in] ap Arguments
@return a number of bytes written to a buffer *excluding* terminating '\0'
@post
The syntax of a format string is generally the same:
% <flag> <width> <precision> <length modifier> <format>
where everithing but the format is optional.
Three one-character flags are recognized:
'0' has the standard zero-padding semantics;
'-' is parsed, but silently ignored;
'`' (backtick) is only supported for strings (%s) and means that the
string will be quoted according to MySQL identifier quoting rules.
Both <width> and <precision> can be specified as numbers or '*'.
If an asterisk is used, an argument of type int is consumed.
<length modifier> can be 'l', 'll', or 'z'.
Supported formats are 's' (null pointer is accepted, printed as
"(null)"), 'b' (extension, see below), 'c', 'd', 'i', 'u', 'x', 'o',
'X', 'p' (works as 0x%x).
Standard syntax for positional arguments $n is supported.
Extensions:
Flag '`' (backtick): see above.
Format 'b': binary buffer, prints exactly <precision> bytes from the
argument, without stopping at '\0'.

value (time_type == MYSQL_TIMESTAMP_TIME) days and hour member can hold
bigger values.

/**
Portable implementation of special type of read-write locks.
These locks have two properties which are unusual for rwlocks:
1) They "prefer readers" in the sense that they do not allow
situations in which rwlock is rd-locked and there is a
pending rd-lock which is blocked (e.g. due to pending
request for wr-lock).
This is a stronger guarantee than one which is provided for
PTHREAD_RWLOCK_PREFER_READER_NP rwlocks in Linux.
MDL subsystem deadlock detector relies on this property for
its correctness.
2) They are optimized for uncontended wr-lock/unlock case.
This is scenario in which they are most oftenly used
within MDL subsystem. Optimizing for it gives significant
performance improvements in some of tests involving many
connections.
Another important requirement imposed on this type of rwlock
by the MDL subsystem is that it should be OK to destroy rwlock
object which is in unlocked state even though some threads might
have not yet fully left unlock operation for it (of course there
is an external guarantee that no thread will try to lock rwlock
which is destroyed).
Putting it another way the unlock operation should not access
rwlock data after changing its state to unlocked.
TODO/FIXME: We should consider alleviating this requirement as
it blocks us from doing certain performance optimizations.
