75ea9ccbea Fixed bug of long strings in binary chunks 
When "undumping" a long string, the function 'LoadVector' can call the
reader function, which can run the garbage collector, which can collect
the string being read. So, the string must be anchored during the call
to 'LoadVector'. (This commit also fixes the identation in 'l_alloc'.)

5027298b46 Added directory 'testes/libs/P1' to the repository 
This directory is used for some tests. As standard Lua has no command
to create directories, it must be present before running the tests.

6d763a2500 'realloc' can fail when shrinking a block 
According to ISO C, 'realloc' can fail when shrinking a block. If that
happens, 'l_alloc' simply ignores the fail and returns the original
block.

f5eb809d3f Fixed missing GC barriers in compiler and undump 
While building a new prototype, the GC needs barriers for every object
(strings and nested prototypes) that is attached to the new prototype.

cee1ebe337 File 'bugs' no longer tracked by git 
The file 'bugs' reports bugs in several different versions
(corresponding to different branches in the repository), without
a clear division of "this bugs belongs to this version". So, it
doesn't make sense to track it along with one (or many) versions.

73c6ff6593 More generic pattern when testing 'string.format'

1221e987fe Bug: Long brackets with a huge number of '=' causes overflow 
A long bracket with too many equal signs can overflow the 'int' used for
the counting and some arithmetic done on the value. Changing the counter
to 'size_t' avoids that. (Because what is counted goes to a buffer, an
overflow in the counter will first raise a buffer-overflow error.)

063d4e4543 Lua 5.3.5 ported to git 
This is the first commit for the branch Lua 5.3. All source files
were copied from the official distribution of 5.3.5 in the Lua site.
The test files are the same of 5.3.4. The manual came from the
previous RCS repository, revision 1.167.1.2.
