Completing snapshot innodb-5.1-ss2438, part 3.

Changes to plug.in structure, some INNODB_CFLAGS improvements for better
maintenance, and some comments and whitespace changes.

Detailed revision comments:

r2433 | vasil | 2008-04-30 12:02:35 +0300 (Wed, 30 Apr 2008) | 5 lines
branches/5.1:

Add vim modeline to hint it that plug.in is a config file
so it can be colorized.
r2429 | vasil | 2008-04-30 11:19:06 +0300 (Wed, 30 Apr 2008) | 10 lines
branches/5.1:

* Use INNODB_CFLAGS insead of cluttering CFLAGS with InnoDB specific
  flags. CFLAGS are used to compile every file in the MySQL source tree.

* Add INNODB_DYNAMIC_CFLAGS to the flags of the dynamic plugin and use
  -prefer-non-pic to make the dynamic plugin faster on i386.

Approved by:	Sunny

r2430 | vasil | 2008-04-30 11:48:35 +0300 (Wed, 30 Apr 2008) | 8 lines
branches/5.1:

Use CFLAGS instead of INNODB_CFLAGS to avoid having incompatible flags
inserted in CFLAGS and INNODB_CFLAGS and to avoid compiling mysql and
innodb with different flags.

Discussed with:	Sunny
